A big subject, indeed the biggest. I would like to advise against taking the Cartesian "Universal Doubt" as a criterion for anything. You'll have noticed that there are all sorts of things which it never occurs to Decartes to doubt; that knowledge is possible, that "truth" and "error" are absolute categories, and that other beings exist, for example. He applies his own criterion in a very partial and disingenuous way. — alan1000
Descartes' cogito argument uses a well-known, time-tested, method of proof viz. reductio ad absurdum. I wonder if his argument makes any sense in paraconsistent logic or within a dialetheistic framework. :chin: — Agent Smith
I sense a pattern here (in the classical logic sense). The idea is to come up/discover a proposition whose falsehood would entail a contradiction. The cogito does just that. I have one viz. there are some truths. — Agent Smith
Pure gold, but it is not clear why you think this approach is primarily "practical", and does not form the basis of ALL knowledge? — alan1000

Maybe using logic at all for this issue is misguided, because to use logic would imply assuming its validity as a source of knowledge, so we’d already assume an answer from the start — Hello Human
But, if we don’t know the foundation for knowledge, how can we know whether the proposed standard must be accepted? We could only support a standard either with knowledge derived from the foundation, or with the foundation itself, but in either case, you already assume something as a foundation. — Hello Human
I have knowledge already, there are things I know. Whether I have a philosophical foundation for this knowledge is irrelevant. I don't need a theory of knowledge to explain how I know things, instead I need to understand the phenomenon of "knowing". — IntrospectionImplosion
A universal theory of knowledge requires certainty about things I don't think we can be certain about — IntrospectionImplosion
1) It's not a "seeming" (= apparent, appearing) inability. It's a logical statement and proposition. He said, "I cannot doubt of my existence while I doubt". Which is true, i.e. one cannot reject that.By using his seeming inability to doubt his own existence to support his proposal for a foundation of knowledge, Descartes effectively presents this inability as a standard to which any proposal for a foundation for knowledge must respect. But, if we don’t know the foundation for knowledge, how can we know whether the proposed standard must be accepted? — Hello Human
either we can know things, or we cannot know anything. If we can’t know anything, then we can’t know whether we can know anything. — Hello Human
And what are those things? — Hello Human

Descartes didn't use that statement "as a foundation of knowledge" or any kind of foundation for that matter. You and other people do. This statement became --I don't know when, but long after Descartes has made it-- "a fundamental element of Western philosophy, as it purported to provide a certain foundation for knowledge in the face of radical doubt." (Wikipedia). See, it is thought of (by people) as a certain foundation for knowledge. So, all that are interpretations. (The Stanford Encyclopedia of Philosophy does not even talk about any kind of "foundation for knowledge".) — Alkis Piskas
This could be a possibility, only that I don't undestand what do you mean by "the ground on which knowledge stands". :smile: An explanation and an example would allow me to undestand it ...One cannot reject that on the grounds of logic. But if we’re searching for the ground on which knowledge stands, it’s at the very least questionable to use logic to guide us in our inquiries. — Hello Human
I find the occasion to mention that the known "Theseus' Ship" is one of the many pseudo-paradoxes, i.e. paradoxes based on wrong interpretation of facts (fallacies, wrong deductions, etc.)e.g. Neurath's Boat

I have not seen the term foundationalism appearing in tit OP.And, with respect to "foundationalism" (OP), what's your point? — 180 Proof
e.g. Neurath's Boat — 180 Proof

Use theorems, proofs and axiomatic systems (i.e. indefeasible reasoning).So what do you think is the most efficient way to gain knowledge about those abstract objects? — Hello Human

BTW, your very interesting topic will offer me the opportunity to learn soon more about the foundation of knowledge, a subject that I had never considered studying up to now. Thank you for this! :smile: — Alkis Piskas
Syād, post-Agrippa('s trilemma) life has been tough for dogmatists. The quest to find a firm foundation for knowledge, the epistemic bedrock as it were, is an ongoing enterprise and the 3 approaches (infinitism, foundationalism, coherentism) still don't qualify as safe harbor. Instead of solving the problem, they merely ignore it. It's kinda like a patient who visits a doctor complaining of a headache, and the doctor, instead of prescribing medication, tells the fellow that, despite the pulsating waves of pain, there's no headache! :snicker: — Agent Smith

One should not understand this compulsion to construct concepts, species, forms, purposes, laws ('a world of identical cases') as if they enabled us to fix the real world; but as a compulsion to arrange a world for ourselves in which our existence is made possible:we thereby create a world which is calculable, simplified, comprehensible, etc., for us.
Our cognitive apparatus is not organized for 'knowledge.'
[T]he aberration of philosophy comes from this:instead of seeing logic and the categories of reason as means to the adaptation of the world to ends of utility (that is, "in principle," for a useful falsification) men believe to possess in them the criterion of truth or reality.
~Nietzsche — Pantagruel
I agree with Habermas, extending this reasoning, that in the context of this "transcendentally-logically conceived pragmatism" there are a wide array of "knowledge-constitutive and knowledge-legitimating interests" beyond the merely logical and technical. — Pantagruel
We cannot put forth foundationalism with certainty. — Manuel
we have a certain mechanism or capacity to acquire knowledge, yet we do not know what these mechanisms are. — Manuel
So we have to begin with consciousness as that with which we have the most confidence of existing and must merely do the best we can with what we are given. — Manuel
when I am thinking, I know that I am thinking and not not thinking, and this is because, when I am not thinking, I still know, at least intuitively, that I possess the a priori potential to begin thinking; hence, I cannot deny the existence of thought without contradiction, and because that which thinks cannot possibly be non-existent, the fact that I think, and know that I think and have the potential to think, implies that I exist as a subject — TheGreatArcanum
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
