As predicted, I’ve been on a stoicism bender. This was a good one to dive into early, as my recent Heraclitus and Seneca might have tipped you off. This bit on friendship was one of my favorite parts:
Nothing, however, gives the mind so much pleasure as fond and faithful friendship. What a blessing it is to have those to whose waiting hearts every secret may be committed with safety, whose knowledge of you you fear less than your knowledge of yourself, whose conversation soothes your anxiety, whose opinion assists your decision, whose cheerfulness scatters your sorrow, the very sight of whom gives you joy! We shall of course choose those who are free, as far as may be, from selfish desires; for vices spread unnoticed, and quickly pass to those nearest and do harm by their contact.
