That we lie successfully to each other is natural; that we successfully lie to ourselves is a natural wonder. And that the three sciences central to human understanding - psychology, anthropology, and sociology - successfully and continually lie to themselves, lie to each other, lie to their students, and lie to the public at large, must constitute a paramount wonder of a scientific century. Were their condition generally known, they would be classified as public drunks.

Molecular biology lies far from the humanistic sciences that I indict. Yet all scientists must accept the responsibility for hiding from public view, so that scientific infallibility may be preserved, the picture that many know so well. It is the picture of cultural anthropology, behaviourist psychology, and environmentalist sociology like three drunken friends leaning against a lamppost in the enchantment of euphoria, all convinced that they are holding up the eternal light when in truth they hold up nothing but each other.
