Psychologically time is seldom homogenous but rather is as full of shapes as space.

The recalling of beautiful things, whether they are your own experiences or the acheivements of others, is a creative act. Simple ideas can be restated by rote; but profound ideas must be recreated by will and imagination.

Creativity is dangerous. We cannot open ourselves to new insights without endangering the security of our prior assumptions. We cannot propose new ideas without risking disapproval and rejection.

Psychologically time is seldom homogenous but rather is as full of shapes as space.

At pains to define liberty, that most resolute of indefinables, our minds fall back on spatial images; on birds, sailboats, and mountains; the untethered balloon, the blue sky, the nude figure.

All great experience has a guarded entrance and a windowless facade.

Such self-transformation is the most difficult and dangerous challenge to the imagination, and it is the most rewarding. Meeting it is only possible for the person whose mind is open to contradictions and well-practiced in free conjecture.
