    Designing smart phones is very different from knowing how life originated. You are not comparing similar things.Truth Seeker

    It was not comparison as such, but again giving you analogy that the scope of knowledge of Phd in Physics or Electronics is very narrow and limited, while there are vast amount of topics in Science and the Universe we don't still know.
  • What can I know with 100% certainty?

    I was not denying the existence of those extraterrestrial entities.  But I was meaning that they are out of reach, and unknowable, no one has been there, no one has tangible proof, so why not limit what we talk about them?  You are free to imagine whatever you want to imagine, but please allow others who are sceptical about them too.

    In the case of the Big Bangs, I am surprised you believe they are real. Have you been there when it happened? Has anyone been there and seen it was happening? It is just a theory not much different from religious claims on some miracles. OK, they will bring all sort of inferences from the other galaxies and blackholes etc with so called "scientific inferences" from the observations made millions miles away, but the bottom line is it is just inference and presumption. It still lacks any type of critical concrete evidence. OK, you still believe it? I will not stop you.

    The real bottom line here seems that my point is trying to limit the debatable subjects to what we can see, touch, smell, and hear, observe and verify in person directly, whereas your ideas mostly come from the media and imaginations.

    It is ok to get info from the media if the subjects are tangible, and exist in daily life such as smartphones or electric cars.  But when the topics are millions miles away from Earth, and no one has been there, or seen on a daily basis (in the case of aliens), if you bring stories from the media, how much more accuracy of information can you get?

    Bear in mind science and technology advances have done good to human life, but there is also an enormous amount of damage done to humans too - I will let you reflect on what they are.  For example Smartphones and your computer will trace everything you type and search on the internet, so your privacy is non-existent, no one in this age has privacy, and you have to admit, and allow that, unless you are someone in the Amazon jungle hunting and fishing for your daily life and family.
    Yeah, the topic is digressing to popular science and technology for some reason. I think you started it :D. These are my least favourite topics, and I was only responding to your cry outs :D
  • What can I know with 100% certainty?
    You said in your reply to my post: "hmmm sci fi speculations. Not sure on these." That's why I asked you to clarify what you mean.

    I know what the concepts mean so no need for me to look them up.
    Truth Seeker

    The Big Bang stories, other galaxies, and aliens ... these stories were in science magazines for teenagers a long time ago, and I used to read them with much interest when I was a teen.
    Now, I am a sceptic, and tend to only believe what I can feel, think, observe and verify.

    There is knowledge from over 100 PhDs that goes into making a smartphone. I don't think you are appreciating the years of research that went into developing these things.Truth Seeker

    Smart phones are just device which is slightly more clever and miniaturised Wireless radio communication device with the touch screens.  Wireless communication has been available since the early 1900s, and it is not really some esoteric black art technology.  Nowadays the companies have mastered how to make them smaller and also adding more extra features due to the digital technology.  But the point is that these devices can be manufactured by any developed country with the available parts and resources.  No need to be hugely impressed with the smart phones, broadband or electric cars ... how they work ins and outs are all in the internet, if you search for them.

    And 100 Ph.d graduates in Physics and Electronics working for the smart phone technologies? But they don't know how the universe began, how and where from life originated, and they will all get old fast, and die one day just like all other humans and species on earth. What is special about them? :D

    You said: "Your sayings are like "Because we built a 300 story building on earth, we could soon build a tower reaching Mars, Jupiter even the other Galaxies."" This is not true. We already have the technology to build a generation ship. We already have the technology to go to Mars. We are trying to reduce the cost of space travel before making the journey to Mars.Truth Seeker

    That was just to give you an analogy to what you were speculating for the future from the current technology, which sounds unrealistic and far-fetched.

    You send a spaceship to Mars costing billions of dollars. It gets there, and it wheels around maybe a few hundred meters on the surface, and take some fuzzy photos and send them to Earth. Take some soil samples to analyse, and then it goes to Sleep mode due to signal failure, and dies. What benefit could these current space technology bring to the living humans on earth?

    Suppose you have landed on Mars. How long can you survive up there without the heavy spacesuit? How long your oxygen, water, and food supply will last? What if you suddenly need emergency surgery due to sudden medical problems? Can you even take shower? To solve all these issues, you need to transport maybe a whole cityful of gear, equipment, supplies and people with you to Mars? It is not logically impossible thing to imagine suppose, but realistically sounds too remote possibility. So where are the truths with 100% certainty you are seeking?

    Do you have any formal educational degree from a university in any branch of science, such as a BSc or BSc (Honours) or MSc or PhD or DSc?Truth Seeker

  • What can I know with 100% certainty?
    What is sci-fi speculation? Big Bang? Other galaxies? Other stars? Black holes? Interstellar travel? Please clarify.Truth Seeker

    I don't feel it is necessary or meaningful for me to clarify or define these concepts. Because they are not controversial, obscure, diverse, or esoteric in nature, as you might agree. They are simple words from Sci Fi, daily use of language and popular science, which everyone knows what they are. They are not controversial nature like the concept of God, afterlife or freewill. If you are really unfamiliar with those terms, and want to find out, then do some Google search, and they will tell you what they are instantly. I personally don't see any philosophical significance or points for defining them unless we are discussing Philosophy of Science topics with these concepts.


    We could use generational ships for interstellar travel. These ships could grow food onboard and have facilities for having children and educating them as they grow and learn while travelling towards another star. We could do this with the current level of technology.Truth Seeker

    If we ever learn to build the warp drives used in Star Trek we could travel much faster than the speed of light. I know that this is science fiction for now. However, television, radio, computers, the internet and mobile phones were science fiction not long ago. They are all real now thanks to science and technology.Truth Seeker

    Well I told you before, that you can imagine or infer anything from these scientific and technological appliances we currently have and use, but the current technology you seem to be impressed so much, and we use are not something which are miraculously complicated or sophisticated.  If you read and study about them a bit, then you will find that they are just technologies which are a bit more clever, and are perfectly possible to be manufactured, marketed and popularised under the normal Earth environments with the available resources.

    But what you are imagining and dreaming as possible reality in the future are totally different in level and calibre of things that are beyond the limit of reality and the law of the universe.

    Just because those technologies you mentioned are available to us within short space of time and the last few decades does not follow logically and realistically all the other possibilities such as living on Mars, visiting other galaxies will be possible by necessity.  If you read and study about the details of these ventures more, what is actually the case, and involved you will know why they are not possible in reality.

    Your sayings are like "Because we built a 300 story building on earth, we could soon build a tower reaching Mars, Jupiter even the other Galaxies."  I would have thought your intuition would tell you immediately, that it is impossibility within the law of the physical universe.
  • What can I know with 100% certainty?
    I am even sceptic if anyone can live in Mars even after hundreds years of trials. They are wasting crazy money on these projects, which actually does harm the Earth environment with the massive amount of fuel they burn each time they shoot the rockets. :sad:
  • What can I know with 100% certainty?
    hmmm sci fi speculations.  Not sure on these.  They just fill the media spaces with these imaginative sayings so they can be paid for the month. :D  OK - they are a million light years away from earth.  How many generations of astronauts and what type of spacecraft will they need? Air and food supplies? Just to get there? :D  I opt to remain sceptic, and just enjoy reading Philosophy. :)
  • What can I know with 100% certainty?
    Sure in that sense, Science is not much different from Mysticism. There are myriads of questions Science cannot answer.

    For instance, they still don't know what is the origin of life, just lots of hypotheses and theories. Blackholes and galaxies? No one can even go near to them. Only see them through the telescopes. Big Bangs? How do you know? Were you there when the bang happened? No !! In all these cases, it is just full of speculations not much different from esoteric religions. :)
  • What can I know with 100% certainty?

    You are welcome my friend :) Ok that's fair enough.But please remember not all scientific knowledge is true.  It starts with premises or hypotheses which may be true or false.  Then they observe the phenomenon, to find the evidence to support their hypotheses.  If it does support, then they make it as theories.

    But the experiments and observations are never conclusive or verifiable beyond doubt. There is always a chance that it may be not true, and get falsified. Because no one can experiment and observe the results under every possible different circumstances in the universe. And the affairs in the universe are all bound to change through time.

    Anyhow, then new theories replace the old ones.  This is science.  I feel that there are many people who blindly trust anything if there is label called "Science".  Philosophers know about this, and they tend to be suspicious of all scientific knowledge. "Philosophy of Science" is a subject which explains on this topic throughly.
  • A Wittgenstein Commentary
    I am not without interest, just not familiar with those, so to what extent that informed or shaped his insights I can’t say.Antony Nickles

    I have a copy of "The Oxford Handbook of Wittgenstein", and one of the chapter is about "Wittgenstein on Religious Belief" by Stephen Mulhall.

    https://global.oup.com/academic/product/the-oxford-handbook-of-wittgenstein-9780199287505?cc=gb&lang=en&#

    I have also met a guy who was reading Witt for exclusively analysing the Religious Literatures such as The Bible and the ancient Buddhist scriptures under Wittgenstein's Philosophy of Religion and Logic. He was a lecturer in Religious Dept. of University in Japan. Not sure if he finished his thesis. But I have seen his book published and being sold in Amazon Japan in Japanese language.

    I don’t have anything more on his thoughts on God.Antony Nickles

    Could it be the case that Wittgenstein's ideas on God have little philosophical significance, or you personally are not interested in his God topic?
  • What can I know with 100% certainty?


    Thank you for your recommendation.  I would love to read and learn about all those subjects, but my interest in reading only lies in Philosophy and Psychology, and it is enough to fill my spare time.

    Yes, they are all different subjects, and you might already know their topics, and methods of studying are totally different from each other.  For instance, if you read and study Physics, you would need all the laboratory instruments costing tens of thousands of pounds. 

    For instance, if you are researching radio waves, and its characteristics under solar storms etc, then you would need radio frequency receivers, transmitters, chokes, dummy loads, SWR meters, generators and various types of antennas installed and set up for your studies and research.

    Philosophy doesn't need all these mechanical electrical instruments, because as you might already know, it uses reasoning, logic and common sense, and it is interested in analysing whether someone's claims are making sense, logical, valid, reasonable or even commonsensical.

    Philosophy is not about blindly and pointlessly agreeing with someone's illogical, unreasonable and delusional claims or ideas.  It is not about showering people with sugar coated consolations and positive encouragement for life, as some people do.

    Philosophy is about seeking logical, reasonable and objectively true solutions to the problems by critical analysis.

    I would recommend you to read "The Central Questions of Philosophy" written by A.J. Ayer on this particular topic.
  • A Wittgenstein Commentary
    I think aphorism is a misscharacterization. They are not meant as individual (independent) statements of something he is arguing is true. He does make statements, but they are speculative (like a hypothesis) with the purpose of your coming to the same conclusion on your own,Antony Nickles

    I have come across some commentators sayings on Wittgenstein's writing being aphoristic, which I agreed with after reading some of his original texts such as TLP and PI.

    The first sentence of TLP starts with a declarative type of sentence "The world is all that is the case."
    and then it goes on, "The world is the totality of facts, not of things." They are quite unusual writing styles for philosophical texts, which can only be described as aphoristic.

    Of course Witt makes his points in his writings, and it is not all 100% aphoristic writing style which fills his books, but we cannot help, but notice the writing style throughout his main books both in TLP and PI.


    He is trying to find out why we want feelings to be objects. He does not address the argument for the existence of God other than looking at the same desire of why Descartes looked to God for the purpose of having something fixed, universal, perfect, as Wittgenstein equates with purity as a goal and standard for knowledge.Antony Nickles

    Witt didn't seem deny the existence of God from this passage in TLP.

    "6.432 How things are in the world is a matter of complete indifference for what is higher. God does not reveal himself in the world." - TLP

    I am not sure which God he was referring to here, but it seems he is admitting the existence of God, and also seems saying God cannot be known by human reason or perception. Could it be the similar stance as Kant's concept of God, which belongs to Thing-In-Itself in CPR?
  • What can I know with 100% certainty?

    I would have thought your genes may control your personality, traits, looks and bodily immunities, but not your momentary actions, speeches, and daily life patterns.

    You may argue or presuppose under the same genes of the other beings or species for your determinism, which sounds too far fetched anyway,  but you cannot push that presupposition to even to the same brain structure and content.  Even in the case of brain transplant of you with some other person or other species, it is doubtful if your actions, speeches or decisions will be dictated by the content of the transplanted brain. Anyhow this is too sci fi topic, which I am not even familiar or knowledgeable with. I am only an amateur hobby philosophy reader, not a biologist, ecologist or definitely NOT a sci fi expert.

    It would be like saying, if you had a dog's body, dog's genes, and dog's brain, then youI would bark rather than talk.  You would be far superior in smelling things than humans.  Of course, you would, but where is philosophical point in those sayings?
  • What can I know with 100% certainty?

    1 and 2 sounds like the biological or ecological topics. 3 4 5 6 sounds like the magical abilities only possible in the Harry Potter movies.

    You were still free that you woke up this morning, powered on your computer or phone, visited the forum, read posts, and wrote your replies. No one or no genes or anything forced you to do so.

    You could have done other things such as gone shopping, meeting your friends, going for a drive, taking out all your books from the shelves and organising them or reading them. But you chose to do otherwise. You have been free. You are free.
  • What can I know with 100% certainty?
    ok, let us suppose still you insist you are not free for the reasons you stated above. But would you not admit that there are huge part of your life which is free? Such as drinking water instead of beer, going for a walk instead of sleep etc etc? In that case should you not then say, at least some part of your life is free, while you feel the other part is not? Would it not be more accurate claim? Outright claiming life is deterministic sounds somewhat confused inaccurate and untrue claim.

    There is part of your life which is deterministic, but there is also part which free. This seems more accurate claim and truth.
  • What can I know with 100% certainty?

    Is it not the case of your free choice to be unfree with all the reasons you stated, why you are not free, therefore that was your free choice not to be free? You are still free.
  • A Wittgenstein Commentary
    Both TLP and PI seems written in richly aphoristic style, which attract broad range of different interpretations by the academics and readers.

    What is his view on mental objects such as fear, anger, joy, hope, doubt ...etc? What is his idea on existence of God?
  • What can I know with 100% certainty?
    If you had dolphine's genes, then you wouldn't be sitting in your room in front of your PC or on the phone typing in English, asking these questions.  And because you would not have human reasoning and linguistic abilities, you wouldn't be asking about free will questions.  Maybe you could be reasoning in your head about these questions, but still you wouldn't be typing the questions in English.

    And of course, you could make lots and lots of presumptions, inferences and imaginations on the metamorphic illusions, but but but you will know yourself, that it is a necessity in your reality that you cannot transform physically and biologically into any one of those beings no matter how much you would wish to.

    You will be forever you, and you know it well for truth, that you cannot change that. This is a determinism and necessity.

    But for you to make simple daily life decisions such as going for a walk, or sleeping, listening to music or reading, you only need your dispositional decision in your mind. And in that regard, you are FREE.  Death of all life cycles is determined. No one can change that.

    So life has deterministic, and also free aspects.  Life is not an atomic object.

    In the words of Sun Tzu from The Art of War: “Know thy self, know thy enemy. A thousand battles, a thousand victories.”RussellA

    Witty is an interesting and significant philosopher, because the issues he had raised were compelling and important.

    I used to read Witty with minor interest, peripheral significance, and not a great deal. But I will be reading him with more attention and focus.

    He definitely has intriguing points, views and arguments in his philosophy . His weakness seems come from the inconsistency between TLP and PI, and his concept of words, objects and the world.

    What does he say about God and religion? I am going to read about that topic in the near future.
  • What can I know with 100% certainty?

  • What can I know with 100% certainty?
    Having been  born, living and dying inevitable deaths are universal fate and destiny no life can escape from.  Only in that sense, life is deterministic.

    But the content of all the lives are unique, random, irreplaceable, non exchangeable, unrepeatable and free.  In that sense all life is both deterministic and free in nature.
  • What can I know with 100% certainty?
    Being an agnostic is perfectly fine, if that is the stance you have decided to take. Nothing wrong with that, especially from a philosophical point of view.

    And of course, by all means you could keep on inferring what would be the case, had you had those people's, animals, aliens genes, DNAs, fates ... etc even in another galaxies or possible worlds or parallel universes. But you should also ask, if you could really take on their genes, DNAs and fates and their lives in your real life?

    Remember, every life is unique, and only valid for once in a lifetime, so there is no definition of individual life. The only definition of life in general terms is, that it is an entity born, lives and destined to die sometime. The content of your life is irreplaceable and unique, and all the individual lives since the start of the universe have been the same - unique, irreplaceable and never to be repeated.

    No problems mate. They are all great philosophers. Their importance in the history of philosophy comes from not the truths they concluded, but from the significant issues they raised, and how they explained the issues with their supporting arguments.

    After reading them, whoever you decide to judge as right, is right.
  • What can I know with 100% certainty?
    You are welcome my friend. :)  If I quickly and roughly try to summarise their points,

    Descarte - Truth and  knowledge comes from your mind, and knowledge is innate. He was a rationalist.

    Hume - Truth and Knowledge comes from your experience of external object and world via impressions and ideas. He was an empiricist.

    Kant - Knowledge comes from outside from your sensation, but it needs concepts in your mind to be able to know and judge what they are. Intuition and imagination combines the externally given sense data with the internal concepts, and allow knowledge and judgments possible.

    Some knowledge is never known to the human mind e.g. God, Freedom and Afterlife etc etc. They are outside of human knowability.  For knowledge of God, the concept is postulated rather than perceived or sensed i.e. it is the world of faith and postulation. Kant didn't deny the existence of God, Freedom and Afterlife etc. He limited the power of human reason and knowability, saying they are in the world of faith and belief, and their existence is postulated rather than reasoned, sensed or perceived.

    Kant tried to combine the rationalist and empiricist and come to a more complete system of epistemology.

    If you want to know more about religious knowledge and God, then I would start with Kierkegaard.

    Yes, exactly. It was Socrates who said it. The dictum is recorded in Plato's Apology.javi2541997

    I feel Socrates was right in saying that. He was the first philosopher in history who turned the philosophical focus into human life i.e. what is life, what is better life, and how one should live, from the wonders of the universe topics which were philosophical trends at the time.

    I read the OP as just a topic of Philosophy of Life rather than some outcry of personal problems.

    Humans have reasoning abilities as well as highly developed linguistic capabilities (which no other species have), hence they do think about life and death, and ask these questions, and philosophers debate on the topic from speculating attitudes.

    We typically sleep for around 6 hours every day, but I wonder what happens to reality when we sleep. Do we wake up in the moment after we fall asleep / lose consciousness?Cidat

    Reality keeps on existing as it has been. To the sleeper, the reality disappears, as he/she enters either into a dreaming state or total black out (unconscious state).

    When waking up, the sleeper's memory will bring the person back into the normal reality that he has been sleeping, not newly born or thrown into the world at that moment.

  • There is no meaning of life
    Questions on the meaning of life have been asked millions of times from ancient times by the Stoics, philosophers of Religion and Existentialism, and it is a perfectly good philosophy topic.

    It is natural and human thing to do for mature adult people to ask such questions at some point in their lives, have thoughts or debates on the topic without having to feel stress, guilt or negativity.

    Seeking the meaning of life is not replacing life with meanings, but trying to find what makes life happy and worthwhile.
  • There is no meaning of life
    Some people are content with just living, and some seek the meaning of life. Each to their own.
    Meaning of life doesn't have to be something grandiose or drastically dramatic.

    Anything, no matter how trivial, one finds happy doing, makes them absorbed, totally oblivious of life and the world could be good enough meaning of life.
