Hello Bob! I'm back from vacation. I hope the holidays found you well.
Your immediateness section is spot on! Our chain of "trusting" memories is the evaluation of possibilities and plausible beliefs. Having a memory of something doesn't necessarily mean that memory is of something we applicably knew. Many times, its plausible beliefs that have not been applicably tested. While I agree that immediateness is an evaluative tool of possibilities (that which has been applicably known at least once), an old possibility is still more cogent than a newer plausibility.
Plausibility does not use immediateness for evaluation, because immediateness is based on the time from which the applicable knowledge was first gained. Something plausible has never been applicably known, so there is no time from from which we can state it is relevent.
Moreover, I would say that immediateness, in a general sense, is "reasonableness". — Bob Ross
The reasonableness is because it is something we have applicably known, and recently applicably known. I say this, because it is easy to confuse plausibilities and possibilities together. Especially when examining the string of chained memories, it is important to realize which are plausibilities, and which are possibilities. If you have a base possibility that chains into a plausibility, you might believe the end result is something possible, when it is merely plausible.
So taking your example of a person who has lived with different memories (A fantastic example) we can detail it to understand why immediateness is important. It is not that the memories are old. It is that that which was once possible, is now no longer possible when you apply your distinctive knowledge to your current situation.
We don't even have to imagine the fantastical to evaluate this. We can look at science. At one time, what was determined as physics is different than what scientists have discovered about physics today. We can look back into the past, and see that many experiments revealed what was possible, while many theories, or plausibilities were floating around intellectual circles, like string theory.
However, as pluasibilities are applied to reality, the rejects are thrown away, and the accepted become possibilities. Sometimes these possibilities require us to work back up the chain of our previous possibilities, and evaluate them with our new context. Sometimes, this revokes what was previously possible, or it could be said forces us to switch context. That which was once known within a previous context of time and space, can no longer be known within this context.
With this clarified, this will allow me to address your second part about plausibility.
Take that tree example from a couple of posts ago: we may never be able to applicably test to see if the tree is there, but I can rationally hold that it is highly plausible that it is. — Bob Ross
Is it possible that the tree is not there anymore, or is it plausible? If you applicably know that trees can cease to be then you know it is possible that a tree can cease to be. It is plausible that the tree no longer exists, but this plausibility is based on a possibility. The devil is in the details, and the devil understand that the best way to convince someone of a lie, is to mix in a little truth.
The reality, is this is a plausibility based off of a possibility. Intuitively, this is more reasonable then a plausibility based off of a plausibility. For example, its plausible that trees have gained immortality, therefore the tree is still there. This intuitively seems less cogent, and I believe the reason why, is because of the chain of comparative logic that its built off of.
But the end claim, that one particular tree is standing, vs not still standing, is a plausibility. You can rationally hold that it is plausible that it is still standing, but how do we determine if one plausibility is more rational than another? How do we determine if one possibility, or even one's applicable knowledge is more cogent than another? I believe it is by looking at the logic chain that the plausibility is linked from.
The validity of a plausibility claim is not about if it is directly applicable to reality or not, it is about (1) how well it aligns with our immediate knowledge (our discrete experiences, memories, discrete knowledge, and applicable knowledge) and (2) its relevancy to the subject. For this reason, I don't think the claim that unicorns exist can be effectively negated by claiming that it is not possible that they exist. — Bob Ross
I think the comparative chains of logic describes how (1) it aligns with our immediate knowledge and inductive hierarchies. I believe (2) relevancy to the subject can be seen as making our distinctive knowledge more accurate.
Going to your unicorn example, you may say its possible for an animal to have a horn, possible for an animal to have wings, therefore it is plausible that a unicorn exists. But someone might come along with a little more detail and state, while its possible that animals can have horns on their head, so far, no one has discovered that its possible for a horse to. Therefore, its only plausible that a horse would have wings or a horn, therefore it is only plausible that a unicorn exists. In this case, our more detailed context allows us to establish that a unicorn is a concluded plausibility, based off of 2 pluasibilities within this more specific context.
Logically, what is pluasible is not yet possible. Therefore I can counter by stating, "It is not possible for a horse to have wings or horns grow from its head. Therefore it is not possible that a unicorn exists in the world."
I am a firm believer in defaulting to not believing something until it is proven to be true, and so, naturally, I don’t believe unicorns exist until we have evidence for them — Bob Ross
I think this fits with your intuition then. What is plausible is something that has no applicable knowledge. It is more rational to believe something which has had applicable knowledge, the possible, over what has not, the plausible.
Now, I think this gets a bit tricky because someone could claim that their belief in a unicorn existing makes them happier and, thereby, it is relevant to them. — Bob Ross
Hopefully the above points have shown why a belief in their existence, based on their happiness of having that belief, does not negate the hierarchy of deductive application and induction. Recall that to applicably know something, they must have a definition, and must show that definition can exist in the world without contradiction. If they give essential properties, such as a horse with a horn from its head and wings, they must find such a creature to say they have applicable knowledge of it.
Insisting it exists without applying that belief to reality, is simply the belief in a plausibility. Happiness may be a justification for why they believe that plausibility, but it is never applicable knowledge.
Happiness of the self does not fulfill the discovery of the essential properties of a horn and wings on a horse in the world.
I would, personally, rephrase “Despite a person’s choice, it does not negate that certain inductions are more rational” to “Despite a person’s choice, it does not negate that certain inductions are more rational within a fundamentally shared subjective experience”. — Bob Ross
I agree with the spirit of this, but want to be specific on the chain comparison within a context. What is applicable, and the hierarchy of inductions never changes. What one deduces or induces is based upon the context one is in. Something that is possible in a specific context, may only be plausible in a more detailed one as noted earlier. But, what is possible in that context, is always more rational then what is plausible in that context.
For example, your #3 (degree of harm) principle doesn’t really address two ideas: (1) the subject may not share your belief that one ought to strive to minimize the degree of harm and (2) the subject may not care about the degree of harm pertaining to other subjects due to their actions (i.e. psychopaths). — Bob Ross
I agree here, because no matter what formula or rationale I set up for a person to enter into a particular context, they must decide to enter in that particular content of that formula or rationale! This means that yes, there will be creatures that are not able to grasp certain contexts, or simply decide not to agree with them. This is a fundamental freedom of every thinking thing.
So then, there is one last thing to cover: morality. You hit the nail on the head. We need reasons why choosing to harm other people for self gain is wrong. I wrote a paper on morality long ago, and got the basic premises down. The problem was, I was getting burned out of philosophy. I couldn't get people to discuss my knowledge theory with me, and I felt like I needed that to be established first. How can we know what morality is if we cannot know knowledge?
Finally, it honestly scared me. I felt that if someone could take the fundamental tenants of morality I had made, they could twist it into a half truth to manipulate people. If you're interested in hearing my take on morality, I can write it up again. Perhaps my years of experience since then will make me see it differently. Of course lets finish here first.
That would be my main point: it is not really about what is "true", but what is "useful" (or relevant). — Bob Ross
I just wanted to emphasize this point. Applicable knowledge cannot claim it is true. Applicable knowledge can only claim that it is reasonable.
And with that, another examination done! Fantastic points and thoughts as always.
