Alternate version" Tradition is the living faith of the dead; traditionalism is the dead faith of the living. Tradition lives in conversation with the past, while remembering where we are and when we are and that it is we who have to decide. Traditionalism supposes that nothing should ever be done for the first time, so all that is needed to solve any problem is to arrive at the supposedly unanimous testimony of this homogenized tradition.

On Literature, Revolution, Entropy and Other Matters (1923)
Context: It is an error to divide people into the living and the dead: there are people who are dead-alive, and people who are alive-alive. The dead-alive also write, walk, speak, act. But they make no mistakes; only machines make no mistakes, and they produce only dead things. The alive-alive are constantly in error, in search, in questions, in torment.
The same is true of what we write: it walks and it talks, but it can be dead-alive or alive-alive. What is truly alive stops before nothing and ceaselessly seeks answers to absurd, "childish" questions. Let the answers be wrong, let the philosophy be mistaken — errors are more valuable than truths: truth is of the machine, error is alive; truth reassures, error disturbs. And if answers be impossible of attainment, all the better! Dealing with answered questions is the privilege of brains constructed like a cow's stomach, which, as we know, is built to digest cud.
