Re: Truth
It seems like logic and math only give us provisional truths. If X=3, then X+5=8. But though we might have broad agreement about the value of X, and there may be an objective fact of its true value, our idea that X=3 is necessarily subjective. Similarly, if we accept meanings of words, then their use gives certain meaning (though the statement itself might still be false).Steve3007 wrote: ↑December 17th, 2018, 7:01 amAre the objective truths of maths and logic simply statements of our determination to use certain symbols in certain ways?

It's just my opinion that objective truth is out there, waiting to be found. Maybe we find it sometimes, yet we never know for sure, for we have nothing which is not subjective which is truly ours. Of everything else we have only impressions.

No. Math and logic are not determined by us, nor is 'man-made' in any way. Math and logic are objective truths, that we then try to express/communicate with symbols (and words) in certain ways.Steve3007 wrote:Are the objective truths of maths and logic simply statements of our determination to use certain symbols in certain ways?
Yes. For it is the agreed upon meanings of these 'labels' (words/symbols/names/squiggle-marks), that really matter, not the 'name/label' given to represent the meaning.Steve3007 wrote:If we cite these as examples of certain truths, can we similarly cite the agreed definitions of words in dictionaries?
Logic/math gives us 'true' (objective) truths, not provisional or subjective truths. --- Analogy: A calculator is an objective tool (much like logic/math), but if we incorrectly use this calculator (i.e. push the 'divide' button instead of the 'multiply') we can get screwy subjective results (false truths).chewybrian wrote:It seems like logic and math only give us provisional truths.

Logic/math, and specifically hunting down 'logical impossibilities', is our best and only means to find truths (other than Descartes "clean slate" method which is severely limited), as there is nothing in this universe that we can be more 'certain' of, than the certainty of a logical impossibility. This, elimination of logical impossibilities from our contaminated pool of knowledge, is therefore the best and most appropriate path to obtaining "true knowledge".

Re: Truth
People can decide if something is true or not, but it is only subjective opinion, not objective fact. Objective facts are only theory. I have the opinion that the are out there, yet can not say 100% when (if) I have found one, even though I think that I know many of them.RJG wrote: ↑December 17th, 2018, 3:22 pm Logic/math gives us 'true' (objective) truths, not provisional or subjective truths. --- Analogy: A calculator is an objective tool (much like logic/math), but if we incorrectly use this calculator (i.e. push the 'divide' button instead of the 'multiply') we can get screwy subjective results (false truths).

Logic does not give truth. It answers an 'if...then...'. The inputs are always necessarily ifs, meaning the outputs are only true "if". I think provisional works, but contingent truth nails it down better. And, logic is only useful for argument if your opponent assents to the cornerstone premise. If you believe A, and A implies B, and B implies C, then C must be true. Nothing that follows matters if you deny A. Logical impossibilities are also contingent on the truth of the inputs (the opinion of such truth held by the person assenting to it, or not).
If you come to me with an "A" that is a load of you know what in my mind, like telling me that people can not think, then the logic that follows won't impress. Or, if your conclusion is such nonsense, then I must assume that your initial premise, or some step along the way, is faulty.
It's nice that you want to escape our real, messy universe of unknowns. Choose a different doorway, and I might go with you. But, you wish to tell me that my very essence is not just in doubt, but rather can not exist, even as I can only receive your corrupted message by putting my reason to use. The essence of man is reasoned choice. It is the foundation of our success, such as it is. I am thinking, Achilles and the tortoise paradoxes aside. The actual process of thought is an unknown, but it's existence is not in doubt. You can not receive my message nor reply without it.
Perhaps the conscious mind is the user, and the unconscious is the calculator or the spreadsheet. None of that would alter the fact that I form opinions about objects and events, and I make choices based upon my opinions. My thoughts don't randomly pop up; I form them (likely through a coordinated effort of layers of consciousness). You can see the same events and form a different opinion (clearly ). The nuts and bolts of the process of forming opinions and making choices is not known, but it is clearly happening.

Agreed.chewybrian wrote:And, logic is only useful for argument if your opponent assents to the cornerstone premise. If you believe A, and A implies B, and B implies C, then C must be true. Nothing that follows matters if you deny A.
Most logical impossibilities are simple contradictions that take the form of X = ~X. For example "married bachelors" -- married men = non-married men" is a direct and obvious contradiction (X = ~X).chewybrian wrote:Logical impossibilities are also contingent on the truth of the inputs (the opinion of such truth held by the person assenting to it, or not).
I agree with you that this is again, contingent on the agreed upon meanings of the terms.
If there is a faulty premise, then the conclusion is not sound. But if the premise(s) are true, and the syllogism (math) is valid, then the conclusion is sound and therefore "logically true", regardless of one's dislike for the conclusion. -- And "dislike" does NOT mean "not-true".chewybrian wrote:If you come to me with an "A" that is a load of you know what in my mind, like telling me that people can not think, then the logic that follows won't impress.

No offense chewy (at least no more offense than you show me), -- to the contrary, it is more likely that you do not want to escape your fantasy (santa claus) world, so as to avoid seeing reality as it truly is.chewybrian wrote:It's nice that you want to escape our real, messy universe of unknowns.
Chewy, these kinds of comments (yours and mine) here are totally unnecessary. These do NOTHING to further the discussion. Moving forward, I hope you (and I) can refrain from such insults, as these only highlight our 'inability' to effectively argue; and make our respective cases. Thank you.

So can you know your thoughts before they pop up into your awareness? We would all like to believe that we are the masters (the scripters/authors) of our thoughts, but this is simply not the case. Firstly, it is not even experientially detectable, and secondly, it is not even logically possible. I've already shown the logical proof (and can present it again if you wish).chewybrian wrote:My thoughts don't randomly pop up…
We can't possibly know our thoughts before we know them. Logically, every single thought (and experience!) that we are conscious/knowing of has ALREADY BEEN SCRIPTED for us. Every thought and experience has 'content'. Without this already scripted 'content', there would be 'nothing' to know of, 'nothing' to be conscious of; 'nothing' to experience.
If EVERYTHING that we are conscious/knowing of has ALREADY been scripted, then there is NOTHING LEFT for us to consciously/knowingly script. ...so now, where do we go from here? Do we then cast stones at the person that made us aware of this truth, or do we suck it up and go on with life, but being a bit wiser.
As I said in earlier posting:
RJG wrote:Although we all seemingly accept logic as our pathway to truth ("true knowledge"), most of us do so 'only' up to a certain point. For example, as in this case of the logical impossibility of "conscious causation", most of us are psychologically unable to accept a logical truth that inevitably strips ourself of power and purpose, for fear that such an existence may not be worthy of existence. The rejection of this logic is very understandable and reasonable.
But if one's innate curiosity for truth is greater than their innate fear of existential unworthiness, then the 'acceptance' of this otherwise rejected logical truth may then be possible. When confronted with a "Danger Ahead" sign on one's path to truth, only those whose curiosity for truth is greater than their fear for safety/security, will continue on past this fearful point. Most others, will denounce this point in the pathway, and turn back around and down the previous comforting pathway, ...a very normal and expected reaction.
But for those that bravely step past this "Danger Ahead" sign (danger point), there is no need or reason to be discouraged or disillusioned of losing a power that we never had. Life's experiences, good and bad, continue nonetheless. Enjoy the good, and endure the bad. At first 'acceptance', this piece of true knowledge (logical truth) wreaks havoc on our emotions, moods, and purpose of being, much like coming off an addicting drug. But after some time, after the initial acceptance, this new piece of true knowledge yields a contentful and better understanding of reality. We feel we are no longer living in a false reality, but now we are a bit wiser, and the experiences of life, good and bad, continue nonetheless. What we've gained is a better understanding of the actions of others and ourselves. The bad guys no longer appear truly bad and deserving of punishment, and the good guys no longer appear truly good and deserving of praise. We are who we are, and we experience what we experience, ...and life is still good, (...and existence is still worthy!)

Re: Truth
Your conclusion makes zero sense if your premise is true. chewybrian cannot decide to throw stones or get on with life. chewybrian cannot make decisions. You can't have it both ways RJGso now, where do we go from here? Do we then cast stones at the person that made us aware of this truth, or do we suck it up and go on with life, but being a bit wiser.
Also wisdom requires judgement. Judgement (good) requires considered decisions and/or sensible conclusions. If decisions are illusory then wisdom must also be illusory.
I mean I know it's logically impossible for you to think and therefore make sense RJG because you cannot think. So I don't personally blame you. You are not free to throw rocks or get on with it as your programming dictates.

The 'experiencing' of wisdom (new thoughts) and judgements (feelings) are still only just experiences, nothing more. You don't 'know' it until 'after' you experience it.

As to the question whether we cause or author our thoughts, I would say that our history and biological structure determine or cause the content of our thoughts, together with the material given to the subject.

I am certainly not implying that chewybrian, or any of us can (consciously) choose our actions. For that is impossible! - I am simply stating that we will take one of two actions, either 1) we'll cast stones, or 2) we'll suck it up.Eduk wrote:So you ask @chewybrian to either throw stones or get on with it.

Re: Truth
I think the whole notion of causing thoughts is misguided. I do not cause myself to walk, and nothing else does either. I do not first do something to cause me to walk and then walk. Nothing else causes me to walk and then I walk. I walk. If I cause myself to walk then I might ask what causes me to cause myself to walk? Some may think that this shows that we do not have free will, but this misses the point.As to the question whether we cause or author our thoughts, I would say that our history and biological structure determine or cause the content of our thoughts, together with the material given to the subject.
I am the author of my thoughts but many of my thoughts are borrowed. For the most part we are not original thinkers, but thinkers nonetheless. We are not ventriloquist dummies. Note, you say “I would say”. No one and nothing is saying that for you or through you. Our history and biological structure are part of who we are. That history and biology does not cause us to think but allow us to think as we do.
