    I never said that complex neurological systems can't be deterministic. As far as I know the decision making process in complex neurological systems is entirely deterministic. Of course, I am not all-knowing. If you can show that our will is not determined and constrained by genes, environments, nutrients, and experiences, then please do. Thank you.
  • What can I know with 100% certainty?
    Thank you for your wise advice.
  • What can I know with 100% certainty?
    I understand the process. Thank you for explaining it.
  • What can I know with 100% certainty?
    Randomness is not free will. Randomness is just randomness.
  • What can I know with 100% certainty?
    I agreed with what LuckyR said because I interpreted his definition to be talking about biological organisms making choices. I can see that you interpreted it differently which is fine.
  • What can I know with 100% certainty?
    Having a will is a prerequisite for having free will. We have a will but it is not free. It is determined and constrained by our genes, environments, nutrients, and experiences.
  • What can I know with 100% certainty?
    That's interesting. I didn't know that a computer program could have 1+1= 257 or -35 etc.
  • What can I know with 100% certainty?
    I agree. Having a will is a prerequisite for having free will. We have a will but it is not free. It is determined and constrained by our genes, environments, nutrients, and experiences.
  • What can I know with 100% certainty?
    Thank you for clarifying what you mean. I agree that people before Galileo and Copernicus used to believe that the Sun orbits the Earth but that didn't make it true. They were simply ignorant of the truth that the Earth orbits the Sun. I don't know what you mean by 1+1=X. Please explain what you mean. Thank you.
  • What can I know with 100% certainty?
    I have read many contradictory definitions of free will and don't agree with any of them. That's why I came up with my own definition. If you don't agree with my definition that's ok with me. I don't ask anyone to agree with me about anything. This is an excerpt of an interview of Robert Sapolski https://www.youtube.com/watch?v=uaxHTYtSavc It is 19 minutes 52 seconds long. You can watch it if you want to. It's fine with me if you don't want to watch it. He is a professor at Stanford University. Please see https://profiles.stanford.edu/robert-sapolsky if you want to know more about him and his research and publications.
  • What can I know with 100% certainty?
    I don't think of statements as judgements. 1 + 1 = 2 is true. The Earth orbits the Sun is true. The Earth orbits Mars is false. These are not judgements. These are truthful statements. An example of a judgement would be: X is guilty of murdering Y.
  • What can I know with 100% certainty?
    There is no universally accepted definition of free will. My definition of free will is a will that is free from determinants and constraints. I clearly don't have free will because my will is both determined and constrained by my genes, environments, nutrients, and experiences. I clearly have a determined and constrained will instead of a free will.

    Did you watch the Robert Sapolsky video?
  • What can I know with 100% certainty?
    Truth is not one's judgement on something. Truth is what is real. If I say that I went to the Moon for a holiday when I actually did not go there, that's a lie. If I say I live on Earth and I actually live on Earth then that's a truth. Hallucinations and dreams are true in the sense that they happen to us and they affect us.
  • What can I know with 100% certainty?
    Thanks for your thoughtful reply. Did you see the Robert Sapolsky video?
  • What can I know with 100% certainty?
    Yes, we do learn the label "dream" from our caregivers. However, that does not preclude the possibility of our perceived reality being dream or hallucination or illusion or simulation. According to Hinduism, our perceived reality is an illusion called Maya. It's impossible to prove or disprove this claim. Of course, just because we can't disprove an idea it does not make it true. It does not make it false either. It is an untestable idea.
  • What can I know with 100% certainty?
    I agree with you. News reports and history books often include selected 'truths' while omitting inconvenient truths.
  • What can I know with 100% certainty?
    If one is convinced that one is right when he or she is wrong, this can lead to catastrophes. I remember a mentally ill person who jumped off a tall building believing that he would fly like Neo flew in the movie called "The Matrix". Sadly, he was severely injured.
  • What can I know with 100% certainty?
    I agree with you but it is still possible that your perceived reality is a simulation or dream or hallucination or illusion. That's why I said I am 99.99% certain that my perceived reality is actually real.
  • What can I know with 100% certainty?
    Please explain why you think: "All the sensory perception I have through my own senses must be taken as 100% truth until they are found, and proven as otherwise via self verification, logical thinking process or repeated observations." Thank you.
  • What can I know with 100% certainty?
    From my perspective. I agree that the world looks flat to me when I am at home on Earth but it won't look flat if I was on the International Space Station.
  • What can I know with 100% certainty?
    Along with shared subjectivity, there is also exclusive subjectivity e.g. only I know the contents of my dreams and what thoughts and recollections occur to me.
  • What can I know with 100% certainty?
    Thank you for the interesting link.
  • What can I know with 100% certainty?
    Thank you for letting me know. I had never Googled shared subjectivity until I read your post. I came up with the concept many years ago when I was discussing reality with my friend.
  • What can I know with 100% certainty?
    Being conscious is a prerequisite for experiencing dream or hallucination or illusion or simulation. That's why I can be 100% certain that I am conscious whether or not my perceptions of reality (e.g. my body, other organisms, the Earth, the rest of the Universe) are of an actual reality or not.

    I created the term "shared subjectivity". It is more accurate than saying "shared reality" because we don't actually know with 100% certainty whether our perceptions of reality are of an actual reality or not.

    What is true at the quantum level is not true at the macroscopic level. We can't measure both the position and vector of electrons but we can measure both the position and vector of footballs. Another example would be quantum superposition https://en.wikipedia.org/wiki/Quantum_superposition This never happens at the macroscopic level. When one tosses a coin, it does not land on both the head and the tail at the same time. It lands on either the head or the tail.
  • What can I know with 100% certainty?
    I am not saying this at all. On the second last post on page three of this thread, I have stated that I know 7 things with 100% certainty.
  • What can I know with 100% certainty?
    I agree with everything you have said except for this statement: "And see, you are bringing it up yourself, invalidating therefore your first statement, i.e. that you are 100% certain that you are conscious!" My statement: "It is possible that what I perceive is either a dream or a hallucination or an illusion or a simulation and not objectively real." does not invalidate my previous statement: "I am 100% certain that I am conscious." My experience of being conscious makes me 100% certain that I am conscious when I am conscious. I don't experience this when I am unconscious. It is possible that my perceptions e.g. I see the computer keyboard and the computer screen as I type these words, are not of an actual reality. It's possible that the keyboard and the screen exist only in a dream or hallucination or simulation or illusion.

    You said that you lost the ball when I mentioned macroscopic determinism. So, I will explain it. Quantum indeterminacy https://en.wikipedia.org/wiki/Quantum_indeterminacy and the Uncertainty Principle https://en.wikipedia.org/wiki/Uncertainty_principle exist. However, this does not lead to indeterminacy at the macroscopic level. We can precisely measure the position and vector of a football even though we can't do that with an electron.

    I agree that our perceptions of reality is subjective but there is such a thing as shared subjectivity e.g. we can both see the Sun and the Moon. So, the Sun and the Moon exist in our shared subjective world. Most humans would say that the existence of the Sun and the Moon is an objective truth because every human with a functioning visual system sees the Sun and the Moon when they are visible.
  • What can I know with 100% certainty?
    So far, I am 100% or completely certain of the following:
    1. I am conscious.
    2. I am typing in English.
    3. I am not all-knowing.
    4. I am not all-powerful.
    5. I change.
    6. I can't do lots of things I really want to do e.g. go back in time and prevent all suffering, inequality, injustice, and deaths and make all living things forever happy.
    7. I do some things even though I don't want to do them.
    Here are some things I have done, currently do or will do even though I don't want to do them:

    1. Breathe
    2. Eat
    3. Drink
    4. Sleep
    5. Dream
    7. Pee
    8. Poo
    9. Fart
    10. Burp
    11. Sneeze
    12. Cough
    13. Age
    14. Get ill
    15. Get injured
    16. Sweat
    17. Cry
    18. Suffer
    19. Snore
    20. Think
    21. Feel
    22. Choose
    23. Be conceived

    25. Remember some events that I don't want to remember
    26. Forget information that I want to remember
    27. Die

    I am 99.99% or almost certain of the following:
    1. I and all the other organisms currently alive will die. Every second brings all organisms closer to death.
    2. My body, other organisms, the Earth and the Universe really exist.
    3. Other organisms e.g. humans, cows, dogs, cats, chickens, pigs, lions, elephants, butterflies, whales, dolphins, etc. are conscious.
    4. Being a vegan is more ethical than being a vegetarian and being a vegetarian is more ethical than being an omnivore.
    5. Gods do not exist.
    6. Souls do not exist.
    7. Reincarnation does not happen.
    8. Resurrection does not happen.
    10. Organisms evolved and were not created by God or Gods.
    11. 99.9% of all the species to evolve so far on Earth became extinct in 5 mass extinctions long before humans evolved.
    12. Humans and other organisms do not have free will. Our wills are determined and constrained by our genes, environments, nutrients, and experiences.
