“He is free who lives as he wishes to live; who is neither subject to compulsion nor to hindrance, nor to force; whose movements to action are not impeded, whose desires attain their purpose, and who does not fall into that which he would avoid.” — Epictetus
Merely having an open mind is nothing; the object of opening a mind, as of opening the mouth, is to shut it again on something solid. — G.K. Chesterton
