I further learned that my brain was modular, and the bits of me that I choose to call "I" don't constitute everything. My own brain could sabotage the values and ideals and that "I" hold so dearly. For a long time I struggled with the idea that everything I believed in and loved was fake, because I couldn't force my body to actually act accordingly. Did I value human life? Why wasn't I doing everything I possibly could to save lives, all the time? Did I value freedom and autonomy and gender equality? Why could I not help sometimes being attracted to domineering jerks?
It took me a while to accept that the newly-evolved, conscious, abstractly-reasoning, self-reflecting "I" simply did not have the firepower to bully ancient and powerful urges into submission. It took me a while to accept that my values were not lies simply because my monkey brain sometimes contradicted them. The "I" in my brain does not have as much power as she would like; that does not mean she doesn't exist.
I've been through this kind of thing before, and Less Wrong did nothing for me in this respect (although Less Wrong is awesome for many other reasons). Reading Ayn Rand on the other hand made all the difference in the world in this respect, and changed my life.
Specifically, her non-fiction work (if you find that sort of thing palatable) provides a lot more concrete discussion of her philosophy.
Unfortunately, Ayn Rand is little too... abrasive... for many people who don't agree entirely with her. She has a lot of resonant points that get rejected because of all the other stuff she presents along with it.
If you've recently joined the Less Wrong community, please leave a comment here and introduce yourself. We'd love to know who you are, what you're doing, what you value, how you came to identify as a rationalist or how you found us. You can skip right to that if you like; the rest of this post consists of a few things you might find helpful. More can be found at the FAQ.

A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site.
