Sorry, I'll read anything. But I'm not going to listen to a lengthy podcast to get one piece of information. Can you give me a time tic for what you're referring to.
Our brains are not evolved for lots of situations we encounter in modern life. That doesn't address the moral implications of our decisions when we're put into those situations. Even if I'm not evolved for lifetime monogamy, that doesn't answer the question: "Should I have an affair and lie to my spouse about it?"

Well, all kinds of things could happen. I think you could make a fine argument that it's moral to reject an agreement you've made only because you were tricked into making it. But that doesn't answer the question we're talking about. The question is: is it moral to break the agreement without telling the other party? Your spouse may very will not want to stay in a marriage with you if you are having sex with another woman. The question is: when, if ever, is it moral to deprive her of that choice?
DoubtingThomas wrote:I know dishonesty is immoral, but sometimes under some circumstances it is better than the truth. I still think affairs are better than abandoning your spouse. You disagree?
I absolutely agree that there are circumstances under which being truthful is not the most moral choice. If I'm hiding Anne Frank in my basement, I think it's absolutely moral to lie to the Gestapo. In fact, it may be immoral to tell the truth.
But my spouse is not the Gestapo, and the hot woman at work isn't Anne Frank hiding from the Nazis.
I think you're setting up a false dichotomy. Let me offer a third choice: tell your spouse in advance you want to change the terms of the marriage and why. Let her choose whether your new terms are acceptable to her. Why is that not more moral than the two alternatives you've given?
“The ideal subject of totalitarian rule is not the convinced Nazi or the dedicated communist, but people for whom the distinction between fact and fiction, true and false, no longer exists.”
