Truth Flashcards
3 major interpretations of truth
- Truth is absolute
- Truth as subjective-a matter of personal opinion (which would make this statement subjective)
- Truth as an unattainable entity
This books uses the following for a definition of truth
truth is a JUDGEMENT which accords with reality, that our knowledge of reality and the fact of reality harmoniously conform, that the integrated systems of ideas which we have in mind correspond in exact detail with the world of reality

adaequatio intellectus et rei
Truth is the adequation of thought to thing
Aristotle and the scholastics
Truth lies not only in the intellect but also in things.
George E Moore
Correspondence theory of truth
defines truth as the correspondence of ideas to reality
Spinoza and Hegel
Coherence Theory of truth
A statement is true if it can be INCORPORATED in an orderly and consistent way within the corpus of propositions
William James
Pragmatic Theory of truth
Pragmatists maintain that a belief is true if it worth committing us to ACTION, and that only such a belief corresponds with reality
“Grant an idea or belief to be true, what concrete differences will its being true make in any one’s actual life”
True ideas are those that we can assimilate, validate, corroborate and verify. False ideas are those we can not.
Truth happens to an idea. It becomes true, it is made true by events.
Alfred Tarski
Semantic Theory of Truth
Truth is predicated of sentences of meta-language (a language which makes symbolic assertions about another language)
Truth is applicable only to sentences and is basically a semantic matter
The sentence “snow is white” may be predicated as true if and only if “snow is white”, that is, a material adequacy must exist between the sentence and the fact
Martin Heidegger
The existential Theory of Truth
though it has other qualities, the ESSENCE of truth is freedom
Truth is unconcealment, the participation in the revealment of what-is-as such
We begin to realize an OVERT and already existing truth
Protagoras of Abdera
- Man’s knowledge of phenomenal world is imperfect because of the imperfections of the human sense
- instruments such as microscopes and detection equipment increase the range of but not the quality of understanding of objects
- What is true for me is true for me and what is true for you is true for you alone
Socrates:My opinion is that truth is absolute
Protagoras:Then you would be right
Gorgias of Leontium
Nihilism
- Nothing exists
- If anything did happen to exist, we could never know it
- If by some accident man should come to know it, he would never be able to convey it to others
If knowledge is unknowable how did you come to know that?
