began TOK by looking at scepticism and problems related to acquiring
knowledge. Following that, we looked at Empiricism, Rationalism
and how knowledge is acquired. Now we are going to look at different
theories of perception.
you see is what you get
his book, Ways of Seeing (BBC and Penguin Bks, London, 1983),
John Berger states the problem of perception nicely:
Seeing comes before words. The child looks and recognises before
it can speak.
But there is also another sense in which seeing comes before words.
It is seeing which establishes our place in the surrounding world;
we explain that world with words, but the words can never undo
the fact that we are surrounded by it. The relation between what
we see and what we know is never settled. Each evening we see
the sun set. We know that the earth is turning away from it. Yet
the knowledge, the explanation, never quite fits the sight.
