James J. Gibson Space Quotations

There has been a great gulf in psychological thought between the perception of space and objects on one hand and the perception of meaning on the other.

The abstract analysis of the world by mathematics and physics rests on the concepts of space and time.

The heart of the problem is not so much how we see objects in depth, as how we see the constant layout of the world around us. Space, as such, empty space, is not visible, but surfaces are.
