A man of knowledge lives by acting, not by thinking about acting... Th — Knowledge

"Reading furnishes the mind only with materials of knowledge; it is thinking makes what we read ours."

"Πάντες ἄνθρωποι τοῦ εἰδέναι ὀρέγονται φύσει. Σημεῖον δ᾽ ἡ τῶν αἰσθήσεων ἀγάπησις: καὶ γὰρ χωρὶς τῆς χρείας ἀγαπῶνται δι᾽ αὑτάς, καὶ μάλιστα τῶν ἄλλων ἡ διὰ τῶν ὀμμάτων. Οὐ γὰρ μόνον ἵνα πράττωμεν ἀλλὰ καὶ μηθὲν μέλλοντες πράττειν τὸ ὁρᾶν αἱρούμεθα ἀντὶ πάντων ὡς εἰπεῖν τῶν ἄλλων. Αἴτιον δ᾽ ὅτι μάλιστα ποιεῖ γνωρίζειν ἡμᾶς αὕτη τῶν αἰσθήσεων καὶ πολλὰς δηλοῖ διαφοράς."

"The improvement of the understanding is for two ends: first, for our own increase of knowledge; secondly, to enable us to deliver and make out that knowledge to others."

"What a man knows should find its expression in what he does. The value of superior knowledge is chiefly in that it leads to a performing manhood."

"O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!"

"Diffused knowledge immortalizes itself."
