All told, the Darwinian notion of the unconscious is more radical than the Freudian one. The sources of self-deception are more numerous, diverse, and deeply rooted, and the line between conscious and unconscious is less clear.

Freud had saddled Western culture with the bizarre notion that the least considered utterances were always, magically, the truest—that reflection added nothing, and the ego merely censored or lied. It was an idea born more of convenience than anything else: he’d identified the part of the mind easiest to circumvent—with tricks like free association—and then declared the product of all that remained to be ‘honest’.
