The quantity and quality of consciousness, one may say, have always been growing throughout geological times. In this respect man, in whom nervous organisation and therefore psychological powers have attained an undisputed maximum, may be considered, scientifically, as a natural centre of evolution of the primates.

Humanity is still advancing; and it will probably continue to advance for hundreds of thousands of years more, always on condition that we know how to keep the same line of advance as our ancestors towards ever greater consciousness and complexity.

Humanity at the centre of the primates, Homo sapiens, in humanity, is the end-product of a gradual work of creation, the successive sketches for which still surround us on every side.
