“You may set it down as a truth which admits of few exceptions, that those who ask your opinion really want your praise, and will be contented with nothing less.”

Chap. 8: "What Is Truth?"
The New Being (1955)
Context: Where else, besides in scholarly work, should we look for truth? There are many in our period, young and old, primitive and sophisticated, practical and scientific, who accept this answer without hesitation. For them scholarly truth is truth altogether. Poetry may give beauty, but it certainly does not give truth. Ethics may help us to a good life, but it cannot help us to truth. Religion may produce deep emotions, but it should not claim to have truth. Only science gives us truth. It gives us new insights into the way nature works, into the texture of human history, into the hidden things of the human mind. It gives a feeling of joy, inferior to no other joy. He who has experienced this transition from darkness, or dimness, to the sharp light of knowledge will always praise scientific truth and understanding and say with some great medieval theologians, that the principles through which we know our world are the eternal divine light in our souls. And yet, when we ask those who have finished their studies in our colleges and universities whether they have found there a truth which is relevant to their lives they will answer with hesitation. Some will say that they have lost what they had of relevant truth; others will say that they don’t care for such a truth because life goes on from day to day without it. Others will tell you of a person, a book, an event outside their studies which gave them the feeling of a truth that matters. But they all will agree that it is not the scholarly work which can give truth relevant for our life.
Where else, then, can we get it? "Nowhere," Pilate answers in his talk with Jesus. "What is truth?" he asks, expressing in these three words his own and his contemporaries’ despair of truth, expressing also the despair of truth in millions of our contemporaries, in schools and studios, in business and professions. In all of us, open or hidden, admitted or repressed, the despair of truth is a permanent threat. We are children of our period as Pilate was. Both are periods of disintegration, of a world-wide loss of values and meanings. Nobody can separate himself completely from this reality, and nobody should even try. Let me do something unusual from a Christian standpoint, namely, to express praise of Pilate—not the unjust judge, but the cynic and sceptic; and of all those amongst us in whom Pilate’s question is alive. For in the depth of every serious doubt and every despair of truth, the passion for truth is still at work. Don’t give in too quickly to those who want to alleviate your anxiety about truth. Don’t be seduced into a truth which is not really your truth, even if the seducer is your church, or your party, or your parental tradition. Go with Pilate, if you cannot go with Jesus; but go in seriousness with him!

1800s, First Presidential Administration (1801–1805)
Context: Yours is one of the few lives precious to mankind, and for the continuance of which every thinking man is solicitous. Bigots may be an exception. What an effort, my dear sir, of bigotry in politics and religion have we gone through! The barbarians really flattered themselves they should be able to bring back the times of Vandalism, when ignorance put everything into the hands of power and priestcraft. All advances in science were proscribed as innovations. They pretended to praise and encourage education, but it was to be the education of our ancestors. We were to look backwards, not forwards, for improvement … This was the real ground of all the attacks on you. Those who live by mystery & charlatanerie, fearing you would render them useless by simplifying the Christian philosophy — the most sublime and benevolent, but most perverted system that ever shone on man — endeavored to crush your well-earned & well-deserved fame.
