“Experience rarely teaches its lessons directly but instead requires interpretation through the filter of preconceived theories, prejudices, and desires. Where these are invincible, facts are weak things.”

as quoted [Viktor Yakovlevich Frenkel, Yakov Ilich Frenkel: his work, life, and letters, Birkhäuser, 1996, 3764327413, 25-26]

Variant: We have spiritual facts and their interpretations by which they are communicated to others, sruti or what is heard, and smṛti or what is remembered. Śaṅkara equates them with pratyakṣa or intuition and anumana or inference. It is the distinction between immediacy and thought. Intuitions abide, while interpretations change.

Context: I may illustrate this by two very different examples of human behaviour: that of a man who pushes a child into the water with the intention of drowning it; and that of a man who sacrifices his life in an attempt to save the child. Each of these two cases can be explained with equal ease in Freudian and in Adlerian terms. According to Freud the first man suffered from repression (say, of some component of his Oedipus complex), while the second man had achieved sublimation. According to Adler the first man suffered from feelings of inferiority (producing perhaps the need to prove to himself that he dared to commit some crime), and so did the second man (whose need was to prove to himself that he dared to rescue the child). I could not think of any human behaviour which could not be interpreted in terms of either theory. It was precisely this fact — that they always fitted, that they were always confirmed — which in the eyes of their admirers constituted the strongest argument in favour of these theories. It began to dawn on me that this apparent strength was in fact their weakness.
