Into this world we're thrown like a dog without a bone. Apparently Jim Morrison penned this lyric after attending a lecture on Heidegger whose concept of thrownness (Geworfenheit) resonated with him. The secret to living a worthy life is finding your bone, the one destined for you. And, in a sense, you don't find it, it finds you: it suddenly appears as though from nowhere, and if you have the balls you grab it, hold onto it, and spend the rest of your life gnawing away until it's given you what you need to slip to the next level.
