Whereas in the present fifth epoch, intellectuality can remain unimpaired even if no pleasure is taken in moral actions, in the sixth epoch, it will be quite different.
In the sixth epoch, that is, from about the third millennium onwards, immorality will have a paralysing effect upon intellectuality.
The mental powers of a man who is intellectual and at the same time immoral will definitely deteriorate and this condition will become more and more pronounced in the future evolution of humanity.
A man who has no morals will therefore have no intellectual power for this will depend entirely upon moral actions, and in the seventh epoch, cleverness without morality will be non-existent.
