This is inaccurate. Everything you want is either something you "can" or "can't" have.

Bjorn Merker says consciousness evolved for finding the intersection three categories kinda like this.

is it just me or does this seem backwards? aren't we more likely to be tempted by things we can have (like the idea of the "perfect crime"), but know we shouldn't, whereas we are more likely to aspire to be something (like an astronaut) that isn't really possible?

echoesandwaves:

I think it might just be differing definitions for "can't". You're not allowed to commit the perfect crime and society is set up to be hostile to that. But you are hypothetically capable of becoming, and allowed to become, an astronaut.
