But it seems to me to be an imperfection in things of beauty, and a weakness in man, if an explanation from the shallow-side has a destructive effect. The horror which we feel for Freudian interpretations is entirely due to our own barbaric or childish naivete, which believes that there can be heights without corresponding depths, and which blinds us to the really "final" truth that, when carried to extremes, opposites meet.

It is a common illusion to believe that what we know today is all we ever can know. Nothing is more vulnerable than scientific theory, which is an ephemeral attempt to explain facts and not an everlasting truth in itself.

Science...is part and parcel of our knowledge and obscures our insight only when it holds that the understanding given by it is the only kind there is.
