What Degas called 'a way of seeing' must consequently bear a wide enough interpretation to include way of being, power, knowledge, and will.
Scientific theories tell us what is possible; myths tell us what is desirable. Both are needed to guide proper action.
Foucault is one of many who want a new conception of how power and knowledge interact. But he is not looking for a relation between two givens, 'power' and 'knowledge.' As always, he is trying to rethink the entire subject matter, and his 'knowledge' and 'power' are to be something else.
We've organized ourselves as cultures, to a large degree, around what we agree we know. And when you have multiple ways of knowing, multiple ways of organizing, the society loses one of its deepest organizational principles.
Scientific knowledge is a kind of discourse.
Quite apart from any conscious program, the great cultural historians have always been historical morphologists: seekers after theforms of life, thought, custom, knowledge, art.
All our knowledge is symbolic.
Moreover, the works already known are due to chance and experiment rather than to sciences; for the sciences we now possess are merely systems for the nice ordering and setting forth of things already invented; not methods of invention or directions for new works.
In India there was a sense of time that does not tick with modern clocks, just as there is a knowledge that is not gained through science and empirical experiments. In the modern West knowledge is of objective, finite particulars in historical time. India recognizes that kind of useful information: it calls it "lower knowledge." Higher knowledge (paravidya) proceeds differently, or rather it doesn't proceed at all but enters history full-blown on the morning of a new creation.
There are two kinds of knowledge, local and universal.
First-world science is one science among many; by claiming to be more it ceases to be an instrument of research and turns into a (political) pressure group.
