There are a few grammatical issues. In the first panel "as such" should be "therefore". The fact that people are not the same is the ground (in a causal sense) of their different experience of emotion. In the second panel, the commas that come after "sadness", "happiness" and "sadness" again, always before the word "due" are less than necessary.Incidentally, panel 2 is very amusing.
Is "horny" an emotion? If it is, men have four.Or is it more of a steady state of being?
Have you been reading Leviathan by Thomas Hobbes, by any chance?
Note from Scott: No, but I have read Leviathan by Scott Westerfeld, which is a very different book.
"Horny" is neither emotion nor state of being. It's a physical law of the universe.
This was great! now i feel like i want to go out and punch somebody in face.
