As for words we’ve lost entirely, how about “thumos”?

When the Bible says “God is love.” You can’t tell me that the word means the same thing as when the gay protesters say “love is love.”

“The phenomenon of the prohibition of questions is becoming clearer in its outlines. The gnostic thinker really does commit an intellectual swindle, and he knows it. One can distinguish three phases in the action of his spirit. On the surface lies the deception itself. It could be self-deception; and very often it is, when the speculation of a creative thinker has culturally degenerated and become the dogma of a mass movement. But, when the phenomenon is apprehended at its point of origin, as in Marx or Nietzsche, deeper than the deception itself will be found an awareness of it. The thinker does not lose control of himself: the libido dominandi turns on its own work and wishes to master the deception as well. This gnostic turning back on itself corresponds spiritually, as we have said, to the philosophic conversion, the periagage of the Platonic sense. However, the gnostic movement of the spirit does not lead to the erotic opening of the soul, but rather to the deepest reach of persistence in the deception, where revolt against God is revealed to be its motive and purpose.”
