“Nothing is so peculiar to wisdom as truth.”

"Self-Poise" p. 130.
Summer on the Lakes, in 1843 (1844)
Context: The better part of wisdom is a sublime prudence, a pure and patient truth that will receive nothing it is not sure it can permanently lay to heart. Of our study there should be in proportion two-thirds of rejection to one of acceptance. And, amid the manifold infatuations and illusions of this world of emotion, a being capable of clear intelligence can do no better service than to hold himself upright, avoid nonsense, and do what chores lie in his way, acknowledging every moment that primal truth, which no fact exhibits, nor, if pressed by too warm a hope, will even indicate. I think, indeed, it is part of our lesson to give a formal consent to what is farcical, and to pick up our living and our virtue amid what is so ridiculous, hardly deigning a smile, and certainly not vexed. The work is done through all, if not by every one.

Variant: Information is not knowledge. Knowledge is not wisdom. Wisdom is not truth. Truth is not beauty. Beauty is not love. Love is not music. Music is the best.

Context: Generally speaking, one can say that motor intelligence contains the germs of completed reason. But it gives promise of more than reason pure and simple. From the moral as from the intellectual point of view, the child is born neither good nor bad, but master of his destiny. Now, if there is intelligence in the schemas of motor adaptation, there is also the element of play. The intentionality peculiar to motor activity is not a search for truth but the pursuit of a result, whether objective or subjective; and to succeed is not to discover a truth.
