This position is made perceptible on two levels: the human sciences do not treat man's life, labour, and language in the most transparent state in which they could be posited, but in that stratum of conduct, behaviour, attitudes, gestures already made, sentences already pronounced or written, within which they have already been given once to those who act, behave, exchange, work, and speak; at another level (it is still the same formal property, but carried to its furthest, rarest point), it is always possible to treat in the style of the human sciences (of psychology, sociology, and the history of culture, ideas, or science)
