Is long term monogamy unnatural for human beings?

[Catholic_Lady]

I voted "not unnatural" on the poll above, for the sake of not getting technical. But I do think monogamy is "unnatural" in a sense, though not in the sense that most people would think of. 

A friend of mine posted an article on facebook once that really spoke to me. I dug it up with a google search, and here's the relevant part:  

Monogamy is not natural. You’re right about that.

It’s supernatural.

It’s above our nature. It might not be realistic. Space flight isn’t realistic, either. If I wanted to be natural, I could live in a hole like a rodent, eat insects, and scamper from one mate to the next, until, after a life of nothingness, I die alone in the cold darkness, decomposing into the dirt without anyone ever noticing. That would be natural. It’s probably pretty realistic, too. So it is fortunate that I am a human being and I am given the chance to transcend the existence of a rat or a lizard. I have the opportunity to experience supernatural things like love, and sacrifice, and commitment.

You say that men are especially ill-suited for monogamy. We are not “biologically fitted” for it. What does that mean, Professor? Do you go about your day and, before deciding on any particular course of action, ask yourself if it is something you are biologically fitted to do? I would say we are biologically fitted to be rational beings. And, as rational beings, we are capable of attaining higher things. Monogamy and loyalty are higher things.

Anyway, that's my full version view on the matter.
