Quotes from A. G. Sertillanges

The life of study is austere and imposes grave obligations. It pays, it pays richly; but it exacts an initial outlay that few are capable of. The athletes of the mind, like those of the playing field, must be prepared for privations, long training, a sometimes superhuman tenacity. We must give ourselves from the heart, if truth is to give itself to us. ?#?Truth? serves only its slaves.

Courage is sustained by calling up anew the vision of the goal.
