THE MEANING OF TRUTH
A SEQUEL TO 'PRAGMATISM'
By William James
PREFACE
THE pivotal part of my book named Pragmatism is its account of the relation called 'truth' which may obtain between an idea (opinion, belief, statement, or what not) and its object. 'Truth,' I there say, 'is a property of certain of our ideas. It means their agreement, as falsity means their disagreement, with reality. Pragmatists and intellectualists both accept this definition as a matter of course.
'Where our ideas [do] not copy definitely their object, what does agreement with that object mean? ... Pragmatism asks its usual question. "Grant an idea or belief to be true," it says, "what concrete difference will its being true make in any one's actual life? What experiences [may] be different from those which would obtain if the belief were false? How will the truth be realized? What, in short, is the truth's cash-value in experiential terms?" The moment pragmatism asks this question, it sees the answer: TRUE IDEAS ARE THOSE THAT WE CAN ASSIMILATE, VALIDATE, CORROBORATE, AND VERIFY. FALSE IDEAS ARE THOSE THAT WE CANNOT. That is the practical difference it makes to us to have true ideas; that therefore is the meaning of truth, for it is all that truth is known as.
'The truth of an idea is not a stagnant property inherent in it. Truth HAPPENS to an idea. It BECOMES true, is MADE true by events. Its verity IS in fact an event, a process, the process namely of its verifying itself, its veriFICATION. Its validity is the process of its validATION. [Footnote: But 'VERIFIABILITY,' I add, 'is as good as verification. For one truth-process completed, there are a million in our lives that function in [the] state of nascency. They lead us towards direct verification; lead us into the surroundings of the object they envisage; and then, if everything, runs on harmoniously, we are so sure that verification is possible that we omit it, and are usually justified by all that happens.']
'To agree in the widest sense with a reality can only mean to be guided either straight up to it or into its surroundings, or to be put into such working touch with it as to handle either it or something connected with it better than if we disagreed. Better either intellectually or practically .... Any idea that helps us to deal, whether practically or intellectually, with either the reality or its belongings, that doesn't entangle our progress in frustrations, that FITS, in fact, and adapts our life to the reality's whole setting, will agree sufficiently to meet the requirement. It will be true of that reality.
