In speaking of evolution it is necessary to understand from the outset that no mechanical evolution is possible.
The evolution of man is the evolution of his consciousness. And 'consciousness' cannot evolve unconsciously.
The evolution of man is the evolution of his will, and 'will' cannot evolve involuntarily.
The evolution of man is the evolution of his power of doing, and 'doing' cannot be the result of things which 'happen.’
- from Gurdjieff
as quoted in P.D. Ouspensky's
In Search of The Miraculous
