To be something, to be himself, and always at one with himself, a man must act as he speaks, must know what course he ought to take, and must follow that course with vigour and persistence.

Context

“Ever at war with himself, hesitating between his wishes and his duties, he will be neither a man nor a citizen. He will be of no use to himself nor to others. He will be a man of our day, a Frenchman, an Englishman, one of the great middle class.
To be something, to be himself, and always at one with himself, a man must act as he speaks, must know what course he ought to take, and must follow that course with vigour and persistence. When I meet this miracle it will be time enough to decide whether he is a man or a citizen, or how he contrives to be both.
Two conflicting types of educational systems spring from these conflicting aims.” source
