"Everything we do is for the purpose of altering consciousness. We form friendships so that we can feel certain emotions, like love, and avoid others, like loneliness. We eat specific foods to enjoy their fleeting presence on our tongues. We read for the pleasure of thinking another person's thoughts."
I know Sam Harris is a neuroscientist that has sold millions of books and has his on podcasts etc., so who am I to disagree with this man. Well, I'm only me, and I still disagree. I don't believe we do things in order to feel emotions, like love, friendship, etc. I think we make these bonds because we feel certain emotions, not the other way around. And I'm not sure how we could alter our consciousness because our consciousness is only aware of stimuli. We can alter the stimuli, but our consciousness is just recording. So what's your question?
