Epictetus on Reason

“Study how to give as one that is sick: that thou mayest hereafter give as one that is whole. Fast; drink water only; abstain altogether from desire, that thou mayest hereafter confirm thy desire to Reason.”

“Knowest thou what kind of speck you art in comparison with the Universe?—That is, with respect to the body; since with respect to Reason, thou art not inferior to the Gods, nor less than they. For the greatness of Reason is not measured by length or height, but by the resolves of the mind. Place then thy happiness in that wherein thou art equal to the Gods.”

“One who knows not who he is and to what end he was born; what kind of world this is and with whom he is associated therein; one who cannot distinguish Good and Evil, Beauty and Foulness,... Truth and Falsehood, will never follow Reason in shaping his desires and impulses and repulsions, nor yet in assent, denial, or suspension of judgment; but will in one word go about deaf and blind, thinking himself to be somewhat, when he is in truth of no account. Is there anything new in all this? Is not this ignorance the cause of all the mistakes and mischances of men since the human race began?”
