Once for all, then, a short precept is given thee: Love, and do what thou wilt: whether thou hold thy peace, through love hold thy peace; whether thou cry out, through love cry out; whether thou correct, through love correct; whether thou spare, through love do thou spare: let the root of love be within, of this root can nothing spring but what is good.
After all, I quite naturally want to live in order to fulfill my whole capacity for living, and not in order to fulfill my reasoning capacity alone, which is no more than some one-twentieth of my capacity for living. What does reason know? It knows only what it has managed to learn (and it may never learn anything else; that isn't very reassuring, but why not admit it?), while human nature acts as a complete entity, with all that is in it, consciously or unconsciously; and though it may be wrong, it's nevertheless alive.
Socrates famously said that the unconsidered life is not worth living. He meant that a life lived without forethought or principle is a life so vulnerable to chance, and so dependent on the choices and actions of others, that it is of little real value to the person living it. He further meant that a life well lived is one which has goals, and integrity, which is chosen and directed by the one who lives it, to the fullest extent possible to a human agent caught in the webs of society and history.
But there is suffering in life, and there are defeats. No one can avoid them. But it's better to lose some of the battles in the struggles for your dreams than to be defeated without ever knowing what you're fighting for.
I have felt a presence that disturbs me with the joy of elevated thoughts; a sense sublime of something far more deeply interfused, whose dwelling is the light of setting suns, and the round ocean, and the living air, and the blue sky, and in the mind of man.
