“I came to the Greeks early, and I found answers in them. Greece's great men let all their acts turn on the immortality of the soul. We don't really act as if we believed in the soul's immortality and that's why we are where we are today.”

“We can’t turn life into a pleasure. But we can choose such pleasures as are worthy of us and our immortal souls.”

“All men's souls are immortal, but the souls of the righteous are immortal and divine.”

“I believe in the immortality of the soul because I have within me immortal longings.”

“And if the truth of all things that are is always in our soul, then the soul must be immortal, so you should take courage and whatever you do not happen to know, that is to remember, at present, you must endeavour to discover and recollect...I cannot swear to everything I have said in this argument – but one thing I am ready to fight for in word and deed, that we shall be better, braver and more active men if we believe it right to look for what we do not know, than if we think we cannot discover it and have no duty to seek it.”

“Friendship, like the immortality of the soul, is too good to be believed. When friendships are real, they are not glass threads or frost work but the solidest things we know.”
