Nietzsche always escaped a question by a physical metaphor, like a cheery minor poet.

He said, "beyond good and evil," because he had not the courage to say, "more good than good and evil," or, "more evil than good and evil." Had he faced his thought without metaphors, he would have seen that it was nonsense.

So, when he describes his hero, he does not dare to say, "the purer man," or "the happier man," or "the sadder man," for all these are ideas; and ideas are alarming.

He says "the upper man," or "over man," a physical metaphor from acrobats or alpine climbers.

Nietzsche is truly a very timid thinker.
