Humanism by itself is kind of a generic concept and is spelled with a lower case h except at the beginning of a sentence. What the professor is talking about is Secular Humanism. I'll admit that there is a small degree of religious-type baggage in it but as TRJF said, we do have the ability to direct our own evolution in a way lower animals cannot. There is nothing but the laws of physics preventing us from self-evolving to god-like heights.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
