Edwina, the story of my life is, that I frequently want  things that donot emerge due to my wanting. But I agree. At least I am a mechanic, so I can know something. Best, Helmut      25. Dezember 2020 um 20:27 Uhr "Edwina Taborsky" wrote: Helmut - I don't think that we can 'want' both

Helmut - I don't think that we can 'want' both democracy and capitalism. Neither emerges due to our 'wanting'. Capitalism is an economic mode that enables a growth economy and population growth. No other economic mode enables either. And democracy is simply a political system

Edwina, so, if we want both democracy and capitalism, we should support individual private enterprises, I agree. And for companies bigger than an individual co-operatives. Otherwise the business-owners cannot become majority. I don´t think, that all knowledge is incomplete. Due to Goedel, as far

Helmut - No, I don't think that Godel's incompleteness theory has anything to do with democracy. After all, if we take as a given, that all knowledge is incomplete [and Peirce would be the first to say this!], then, we'd have to question other historical forms of governance - such as a

Helmut, List: I am still having trouble following you here. Intuitionistic logic does not have anything to do with belief or truth, except as a formal system for drawing valid deductive inferences such that the conclusion is true as long as the premisses are true. Its main difference from

Steven, List: SS: Notice the large amount of leeway given in this notion of “justified true” belief: There is indeed considerable leeway for "justified" since it can range from merely plausible for abduction/retroduction to probable for induction to certain for deduction. Even in the last case,

Jon, List,   the fallacy of intuitionistic logic in my hypothesis is, that it first includes belief into the concept of truth, then sees, that belief is not two-valued, and then denies the law of the excluded middle for both. But the NOT-operator can only be applied for truth-problems, and so

Jon Schmidt, We appear to state the same things. Notice the large amount of leeway given in this notion of “justified true” belief: justified true belief justified if it is the conclusion of a valid argument (note: valid argument includes mere plausibility) a belief is true if the

Helmut, Steven, List: HR: For me it is not clear, what exactly is claimed to justify intuitionistic logic. What would it mean to *justify* intuitionistic logic? What kind of reasoning would one use to do so? From my standpoint, it is "justified" by not imposing excluded middle as if it were an

      Correction: I guess I meant "operator" instead of "quantor". I am not a certified logician. Steven,   yes, I nearly totally agree. Interesting, that Goedel said that. An observer cannot know the onologic state of a system the observer is part of. Then calling it knowledge is false, it

Helmut, I think I follow. You guys are clearly expert logicians, but it is easy to get so far into the weeds the way out is lost forever. Now the problem with knowledge is, to call it a classification, there cannot be knowers besides knowers-that-not about one topic. Yes. Logic can kill you.

List,   For me it is not clear, what exactly is claimed to justify intuitionistic logic. Is it the not yet done proof, is it the weak negation, or is it habout handling concepts?   If it is the not yet achieved proof, I think, that is nominalism, isnt it? And it can easily, by induction, be
