Philosophy is not a popular topic at brunches and nor should it be. Learning how to die is not a merry subject. A truly enlightening conversation is often an uncomfortable one and thus an impolite one. In fact, the best time to talk philosophy is after your audience has consumed a bongs-worth of weed. In that case, everyone is too stoned to remember how rude you were.
For the introspective few, philosophy and truth feel like an inescapable pursuer. The muse sticks with you like an earworm. It's a form of possession which drives its host deeper and deeper into the woods. In Christianity, this possession is called the indwelling of the Holy Spirit. Non-Christians don't agree on a word for it but are affected by it just the same.
