Their knowledge and familiarity within a given field or area of knowledge command respect and allow their statements to be criteria of truth. A person may not simply declare themselves an authority, but rather must be properly qualified. Despite the wide respect given to expert testimony, it is not an infallible criterion. For example, multiple ...
Hence, the statement "p is an unknown truth" cannot be both known and true at the same time. Therefore, if all truths are knowable, the set of "all truths" must not include any of the form "something is an unknown truth"; thus there must be no unknown truths, and thus all truths must be known. This can be formalised with modal logic.
Pragmatism describes an indicator or a sign of truth. It really cannot be regarded as a theory of the meaning of the word "true". There's a difference between stating an indicator and giving the meaning. For example, when the streetlights turn on at the end of a day, that's an indicator, a sign, that evening is coming on. It would be an obvious ...
Truth or verity is the property of being in accord with fact or reality. [1] In everyday language, it is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.
This rules out the possibility that by "to be a man", "not to be a man" is meant. But "man" means "two-footed animal" (for example), and so if anything is a man, it is necessary (by virtue of the meaning of "man") that it must be a two-footed animal, and so it is impossible at the same time for it not to be a two-footed
Infallibilism should not be confused with the universally accepted view that a proposition P must be true in order for someone to know that P. Instead, the infallibilist holds that a person who knows P could not have all of the same evidence (or justification) that one currently has if P were false, and therefore that one's evidence ...
In epistemology, the Münchhausen trilemma is a thought experiment intended to demonstrate the theoretical impossibility of proving any truth, even in the fields of logic and mathematics, without appealing to accepted assumptions. If it is asked how any given proposition is known to be true, proof in support of that proposition may be provided ...
In his licentiate thesis, Edouard Guilloux says that it is shown from the study of language "that there can be a gap between what a speaker means when he utters a given sentence and the literal meaning of that same sentence", yet "the literal meaning of a sentence must be apt to convey what the speaker means: the speaker cannot authentically be ...
