The problems of life are solved by the life process itself.

By acting in a certain way, man comes into intimate relationship with the great reality of life, and then he comes to know, not so much _about_ reality, as _within_ reality.
The ant in whom such complex instincts are developed, knows probably nothing at all _about_ its little world, but knows everything necessary _within_ its little world.

It does not err, it does the right thing at the right time, and that because it is in tune with its universe, hence acts from pure instinct in the right way.

If intellect were to enter into the case, its actions might become less reliable, and it would blunder far oftener.

In the case of man, his thinking capacity often militates against successful instinctive and habitual actions--the moment we start to consider, we hesitate and are lost.
