Since we don't know about the lies we tell ourselves, it would have to be "lies I see other people telling themselves".
And that pretty much translates to "Things that other people believe that I disagree with", which is a fairly boring topic for an essay.
a) Sex (e.g., Do you satisfy your partner?) b) Death (e.g., Was your life meaningful?) c) Formal Education (e.g., If not, then what?) d) Identity (e.g., Who are you?) e) Authority (e.g., Who tells you what to do?)
I don't know, honesty seems much harder than settling on lies to tell ourselves.
I take the point that avoiding self-deception is hard, maybe impossible. But that's no different from talking about science, or history, or just about anything else.
That isn't to deny that a pg contribution could be illuminating!
If you don't have time for something, it just means you didn't make time for it. Despite what you think, it's not that valuable to you because you don't choose to do it.
I realized that by not exercising, I was explicitly saying my health or energy level were not important. Since that's just plain dumb, I started going to the gym 3x/week, and I'm going to start biking again soon.
Seems like many of the things discussed have their origin in lies we continue to tell ourselves. Kids just get special versions. But if anything those instances provide a window into what we don't discuss honestly - sex, death, identity, formal education, and obeying authority.
