“Experience teaches us that the eye may be subdued and forced into forming and disposing of objects even quite contrary to what it would naturally see them, by pre judgement of the mind or some other persuasive motive.”

By the time our children are old enough to examine the evidence, our propaganda has closed their minds.

Ideology and Utopia (1929)
Context: This first non-evaluative insight into history does not inevitably lead to relativism, but rather to relationism. Knowledge, as seen in the light of the total conception of ideology, is by no means an illusory experience, for ideology in its relational concept is not at all identical with illusion. Knowledge arising out of our experience in actual life situations, though not absolute, is knowledge none the less. The norms arising out of such actual life situations do not exist in a social vacuum, but are effective as real sanctions for conduct. Relationism signifies merely that all of the elements of meaning in a given situation have reference to one another and derive their significance from this reciprocal interrelationship in a given frame of thought. Such a system of meanings is possible and valid only in a given type of historical existence, to which, for a time, it furnishes appropriate expression. When the social situation changes, the system of norms to which it had previously given birth ceases to be in harmony with it. The same estrangement goes on with reference to knowledge and to the historical perspective. All knowledge is oriented toward some object and is influenced in its approach by the nature of the object with which it is pre-occupied. But the mode of approach to the object to be known is dependent upon the nature of the knower.

yes - but it seems to me that we see more and more that we are not good, no more than the world in general, of which we are an atom - and the world no more good than we are. One may try one's best, or act carelessly, the result is always different from what one really wanted. But whether the result be better or worse, fortunate or unfortunate, it is better to do something than to do nothing. If only one is wary of becoming a prim, self-righteous prig - as Uncle Vincent calls it - one may be even as good as one likes.
