This explains why a certain style of philosophy (popular on forums) leaves more practically minded people cold. — T H E
Agreed, in principle. Not just here, but practically-minded folks in general, usually consider the objects of their inquiries to be given, re: Peirce’s “first sensations”, hence propositions with respect to such inquiries are considered “perfectly free from all actual doubt”.
On the other hand, that which leaves the practically-minded cold, so to speak, becomes moot for them, from sheer disregard. When presented with these conditions, with respect to Peirce’s “first principles”......
“....Human reason, in one sphere of its cognition, is called upon to consider questions, which it cannot decline, as they are presented by its own nature, but which it cannot answer, as they transcend every faculty of the mind. It falls into this difficulty without any fault of its own. It begins with principles, which cannot be dispensed with in the field of experience, and the truth and sufficiency of which are, at the same time, insured by experience. With these principles it rises, in obedience to the laws of its own nature, to ever higher and more remote conditions. But it quickly discovers that, in this way, its labours must remain ever incomplete, because new questions never cease to present themselves; and thus it finds itself compelled to have recourse to principles which transcend the region of experience, while they are regarded by common sense without distrust. It thus falls into confusion and contradictions, from which it conjectures the presence of latent errors, which, however, it is unable to discover, because the principles it employs, transcending the limits of experience, cannot be tested by that criterion....”
.....leaves them to simply not bother inquiring into those kinds of questions predicated on some doubt or other. So, no, this is not reason as madness tamed, but reason as madness denied**, madness herein indicating irreconcilable doubt. With this view, of course, your “doubt as a paralyzing, unpleasant state”, doesn’t exist in the practically-minded domain, but instead manifest as mere complacency, but runs amok, that is to say, “....has fallen into confusion, obscurity, and disuse from ill directed effort....” in the theoretically-minded domain, called pure metaphysics.
** not so much extinguished, as you say, for I think to extinguish presupposes the reality of madness extant beforehand, whereas to deny merely presupposes the possibility.
Anyway.....fun, this philosophy stuff, where good/bad is the proper standard, over right/wrong.
