All knowledge is a function of them. We are enclosed in prisons of subjectivity, and our world view is determined by the historical and cultural setting in which we find ourselves. Inasmuch as we are trapped within our subjectivity, the meanings of our words are self-referencing . Our concepts are not derived from objects as they are in the world, for we cannot know them as they are . Rather, they are derived from their relation to other concepts .
Words take their meanings from other words rather than by virtue of their representative character.
Vocabularies acquire their privileges from the men who use them rather than from their transparency to the real. For if the constituent concepts vary from one framework to another, so too will the truths expressible within each framework vary. We have already seen that there is no such thing as brute, objective fact. Objects are never known as they are in themselves , but only as they are experienced by us . It can t even recognize its mother s face.
