Self-reverence, self-knowledge, self-control - these three alone lead to power

Self-reverence, self-knowledge, self-control - these three alone lead to power

Self-reverence, self-knowledge, self-control; these three alone lead one to sovereign power.

The happiness of a man in this life does not consist in the absence but in the mastery of his passions.

Knowledge comes, but wisdom lingers.

This gray spirit yearning in desire/ To follow knowledge like a sinking star,/ Beyond the utmost bound of human thought.
