Equality in the number of parts of the successive circles in a flower.

Graphic design, which evokes the symmetria of Vituvius, the dynamic symmetry of Hambidge, the asymmetry of Mondrian; which is a good gestalt, generated by intuition or by computer, by invention or by a system of coordinates, is not good design if it does not communicate. Paul Rand
It is the harmony of the diverse parts, their symmetry, their happy balance; in a word it is all that introduces order, all that gives unity, that permits us to see clearly and to comprehend at once both the ensemble and the details. Henri Poincare
Beauty is our weapon against nature; by it we make objects, giving them limit, symmetry, proportion. Beauty halts and freezes the melting flux of nature. Camille Paglia
The universe is built on a plan the profound symmetry of which is somehow present in the inner structure of our intellect. Paul Valery
So that ideas of sort of relaxed symmetry have been something for years that I have been concerned with because I think that symmetry is a neutral shape as opposed to a form of design. Robert Rauschenberg
