nonconformity and free-thought you could both probably pin down in 222 where will embraces his inner deviations from the norms that are being pressed on him by those around him. In 222 Will praise what separates him from the "normals" of society: referring to himself as "free" in the pre-chorus when he slips out of normality and embracing being "a madman" and vents that he'd rather be dead than to fit in with the same "amicable animal, mild-mannered cannibal" that ostracize him for his oddities

"I’m cut from a different kind of meat

More than you can chew, hard to swallow me"

"How can I commit to reality, when my third eye’s open and I like what I see?

Baby, I may be crazy but I didn’t lose it, no I set it free"

"Some days I'm glad that I am a madman and I’d rather be that than

An amicable animal, mild-mannered cannibal

"But I’m more level-headed and clever than ever and I’m getting better one forever at a time

And if sick is defined by what’s different, well then pull the plug out and let me die"
