An aged man is but a paltry thing, a tattered coat upon a stick

Certainty

The best lack all conviction, while the worst are full of passionate intensity.

Death and Dying

I balanced all, brought all to mind, the years to come seemed waste of breath, a waste of breath the years behind, in balance with this life, this death.

Fanatics and Fanaticism

I carry from my mother's womb a fanatic's heart.

Happiness

Happiness is neither virtue nor pleasure nor this thing nor that but simply growth, We are happy when we are growing.

Love

A pity beyond all telling is hid in the heart of love.

Perfection

The intellect of man is forced to choose perfection of the life, or of the work, and if it take the second must refuse a heavenly mansion, raging in the dark.

Reason

The only business of the head in the world is to bow a ceaseless obeisance to the heart.
