Absolutely not. Presuppositions that ground what you say and do, and absolute presuppositions that stand in relation to those things as being like axioms. Nothing whatsoever unwarranted or biased about them. — tim wood

Point taken. I may have missed your intention in the OP. Yet, in my experience, the term "presupposition" is typically used as a negative assessment of someone else's unwarranted beliefs. However, in the usage by Christian Apologists, it is intended to imply a positive meaning : faith in the Judeo-Christian God.

However, I suppose the positive or negative inflection is, as usual, in the mind of the Apologist, or Denier for the belief in question.. Anyway, I would tend to use "Axiom" as a more neutral (and scientific) way to label a self-evident assumption that is taken as true, prior to (pre-) empirical evidence. For Christians, the existence of God is axiomatic. Therefore, to me, "absolute presupposition" implies unshakable faith, not subject to counter evidence. Which may also be the case for mathematicians, who believe that mathematical "objects" absolutely exist as metaphysical ideals.

Do Mathematical Objects Exist? :
I am slowly working on an article for Skeptical Inquirer about the ways in which religious apologists use mathematical arguments in their rhetoric.

I don't mean to harp on one note, but I didn't interpret the topic of this thread as referring to pragmatic mathematical axioms -- that are "rationally adequate for a reflective task". Instead, I thought it was referring to presumptuous beliefs and attitudes. Which implies an unshakable faith in what is True and Real.

Although Kant asserted that ultimate Reality is beyond the scope of human senses, I didn't get the impression that he was being Presumptuous. But merely making an unprovable Supposition for philosophical purposes. We can reason to hypothetical "facts" (conclusions) that we can't actually see or touch. As with Darwin's real-world observations, the "real" evidence may only add-up to a reasonable "theory" much later. Even then, it's "only" a theory, not an observable fact.

Maybe your debate with 180 about seeing a tree is based on presumed meanings applied to different contexts. "I see a tree" versus "I believe there is a tree behind that wall". One statement is grounded in sensory data (real), the other in imagination or memory (ideal). :smile:

Presumptuous :
1. The definition of presumptuous is taking things for granted or being overconfident.
2. (of a person or their behavior) failing to observe the limits of what is permitted or appropriate.


"To my mind, a philosophical expression amounts to a supposition – 'Suppose X, then possibly Y' – that is, a proposal for reflective consideration (e.g. dialectics, gedankenexperiment, daily (fitness / therapeutic) praxis, etc) tested only by its comparatively rational adequacy for some reflective task, and not a proposition asserting what is or not a fact of the matter." — 180 Proof
