“For ages, when philosophers talked about the core of man they referred to it as his "essence," something fixed in his nature, deep down, some special quality or substance. But nothing like it was ever found; man's peculiarity still remained a dilemma. The reason it was never found, as Erich Fromm put it in an excellent discussion, was that there was no essence, that the essence of man is really his paradoxical nature, the fact that he is half animal and half symbolic.”
