The study of the conditions of conscious knowledge (Adapted from W. DILTHEY: Gesammelte Schriften, 1922-1935)
This is a step forward from SOCRATES "Gnoti seauton", His membership of the Athenian culture of his time was implicit for him and at the same time subtly preforming his way of being and thinking,
Such cultural and historical conditions are proper to any individual observer.

He also quotes BENCKE and says: "thought as such�analyses experience"�of course within the already acquired mental and conceptual frame.
