For the most part, I really enjoyed this book and thought it made a lot of good points about the merits of being nice in a society where it is frequently looked down on. But I did get thrown off on the sections about Lying and Being Open-Minded. In Lying, he uses the example that someone can cheat and lie about it and that's nice because they're protecting the feelings of their partner as their partner would most certainly assume that they didn't love them and subsequently end the relationship. While it's true that you can sleep with someone else casually and still love your partner, I found this to be very problematic as it seems to almost put the blame on the partner for the fact that they would feel hurt and they would end the relationship, suggesting that those are unnecessary and the partner is just not as smart or open-minded for being unable to understand that their cheating partner could still love them (the same way it would be difficult for your theoritcal aunt to understand that you didn't like her cake but did love her). But if you would consider this cheating, then you are in a relationship where you have defined boundaries and have therefore disrespected those boundaries. And so if your bigger truth was that you cared about your partner and wanted the best for them, not only would you probably never have sacrificed those boundaries for temporary pleasure, but you would also recognize that they might not be being ridiculous to want to be in a relationship with someone who will respect those boundaries in the future and that might be better for them than being in a relationship with you. Now everyone makes mistakes and you and your partner might be able to work through this or they may see things exactly as you do and not care, but by lying you are really protecting yourself more than your partner and justifying it in an entitled way where you believe your philosophical understanding of love is more developed and self-realized than theirs is. The point being, yes, it is okay to make mistakes and okay to lie occasionally, but it's not okay to decide someone else's boundaries are silly and that you know better than they do what will make them happy.
