After a million years, of fifty thousand years, have we changed deeply? Aren't we very primitive, barbarous? So I am asking if you will consider whether there is psychological evolution at all? I question it. Personally, to the speaker, there is no psychological evolution; there is only the ending of sorrow, of pain, anxiety, loneliness, despair and all that. Man has lived with it for a million years. And if we rely on time, which is thought - time and thought go together - if we rely on evolution then another thousand years or more, and we will still be barbarous.
