"that allow us to deprive ourselves of all experiences of true intensity or meaning" It seems that people have a largely irrational, intense fear of something.

"that allow us to deprive ourselves of all experiences of true intensity or meaning" It seems that people have a largely irrational, intense fear of something. Public speaking, heights, spiders - whatever your fear is if you embrace it you can still (safely) find that incredibly intense experience you are talking about. For me it was skydiving. I get sweaty palms even thinking about heights, going up in a plane with an open door was terrifying! Leaving it was incredible. If you're afraid of spiders, pick up a big one, public speaking? Join toastmasters. You don't need war to experience the thrill of death.
