Antonio D.

“The man who shuns and fears everything and stands up to nothing becomes a coward; the man who is afraid of nothing at all, but marches up to every danger becomes foolhardy. Similarly the man who indulges in pleasure and refrains from none becomes licentious (akolastos); but if a man behaves like a boor (agroikos) and turns his back on every pleasure, he is a case of insensibility. Thus temperance and courage are destroyed by excess and deficiency and preserved by the mean.”
― Aristotle , The Nicomachean Ethics

“Above all, don't lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love.”
― Fyodor Dostoevsky, The Brothers Karamazov

“Though nothing can bring back the hour
Of splendor in the grass, of glory in the flower;
We will grieve not, rather find
Strength in what remains behind;
In the primal sympathy
Which having been must ever be...”
― William Wordsworth
