Science is not a special sense. It is as wide as the literal meaning of its name: knowledge. - Jacob Bronowski

In trying to formalize a rule, we look for truth, but what we find is knowledge, and what we fail to find is certainty. This limitation has no special bearing on the knowledge of self.

The progress of science is the discovery at each step of a new order which gives unity to what had long seemed unlike. Faraday did this when he closed the link between electricity and magnetism. Clerk Maxwell did it when he linked both with light. Einstein linked time with space, mass with energy, and the path of light past the sun with the flight of a bullet; and spent his dying years in trying to add to these likenesses another, which would find a single imaginative order between the equations between Clerk Maxwell and his own geometry of gravitation When Coleridge tried to define beauty, he returned always to one deep thought: beauty he said, is "unity in variety." Science is nothing else than the search to discover unity in the wild variety of nature — or more exactly, in the variety of our experience.

But we are in any case mistaken if we think of our picture of the world as a passive record. The picture is made by, it is made of, our activity, all the way from the logic of the brain to the use of the plow and the wheel.
