So Jarod is suggesting that there is no such thing as love since everything is chemically based.
I don't think that was his reasoning. But more to the point, I don't think anyone holds that position. In fact, I'd say it's just the opposite. Sure, everything in our body is chemically based. So, biologically speaking, "love" is actually a pattern of electro-chemical reactions in our brain. It doesn't mean that love doesn't exist, or that it's unimportant. For comparison: chemically speaking, the
Mona Lisa is just a pattern of pigments on a piece of cloth. It doesn't detract from its awesomeness even one bit. In fact, I would say it's just
amazing that such beauty and intensity could be composed by such simple elements. I see love, or any other affection, in just the same way.
