I think self-knowledge is the rarest trait in a human being.

The one self-knowledge worth having is to know one's own mind.

To have real knowledge, one must understand the essence of things and not only their manifestations.

Self-discovery is above all the realization that we are alone: it is the opening of an impalpable, transparent wall - that of our consciousness - between the world and ourselves.

To know ourselves, is agreed by all to be the most useful Learning; the first Lessons, therefore, given us ought to be on that Subject.

A true knowledge of ourselves is knowledge of our power.

Self-knowledge comes from knowing other men.

How pathetically scanty my self-knowledge is compared with, say, my knowledge of my room. There is no such thing as observation of the inner world, as there is of the outer world.

People need to know that they have all the tools within themselves. Self-awareness, which means awareness of their body, awareness of their mental space, awareness of their relationships - not only with each other, but with life and the ecosystem.

In truth, to know oneself seems to be the hardest of all things. Not only our eye, which observes external objects, does not use the sense of sight upon itself, but even our mind, which contemplates intently another's sin, is slow in the recognition of its own defects.
