Setting Quotes - page 15
No criticism can be brought against a branch of technical science from outside; no thought fitted out with the knowledge of a period and setting its course by definite historical aims could have anything to say to the specialist. Such thought and the critical, dialectical element it communicates to the process of cognition, thereby maintaining conscious connection between that process and historical life, do not exist for empiricism; nor do the associated categories, such as the distinction between essence and appearance, identity in change, and rationality of ends, indeed, the concept of man, of personality, even of society and class taken in the sense that presupposes specific viewpoints and directions of interest.
Max Horkheimer
Now, without directly altering the existing condition of things, it is possible to work upon the human mind and character, and give them a direction no more correspondent with that condition; and this it is precisely which he who is wise will endeavour to do. Only in this way is it possible to reproduce the new system in reality, just as it has been conceived in idea; and in every other method (setting aside the evils which arise from disturbing the natural order of human development) it is changed, modified, disfigured by the remaining influence of preceding systems, in the actual state of circumstances as well as in the minds of men. But if this obstacle be removed,-if the new condition of things which is resolved upon can succeed in working out its full influence, unimpeded by what was previously existing and by the circumstances of the present on which this has acted,-then must nothing further be allowed to stand in the way of the contemplated reform.
Wilhelm von Humboldt
