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 ...
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 ...
Richard McKay Rorty (October 4, 1931 – June 8, 2007) was an American philosopher and historian of ideas.Educated at the University of Chicago and Yale University, Rorty's academic career included appointments as the Stuart Professor of Philosophy at Princeton University, the Kenan Professor of Humanities at the University of Virginia, and as a professor of comparative literature at Stanford ...
A nominal definition explains the meaning of a linguistic expression. A real definition describes the essence of certain objects and enables us to determine whether any given item falls within the definition. [85] Kant holds that the definition of truth is merely nominal and, therefore, we cannot employ it to establish which judgements are true.
Proposition 6.54, then, presents a difficult interpretative problem. If the so-called 'picture theory' of meaning is correct, and it is impossible to represent logical form, then the theory, by trying to say something about how language and the world must be for there to be meaning, is self-undermining.
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 ...
Truth-conditional semantics is an approach to semantics of natural language that sees meaning (or at least the meaning of assertions) as being the same as, or reducible to, their truth conditions. This approach to semantics is principally associated with Donald Davidson , and attempts to carry out for the semantics of natural language what ...
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.
