Studying Philosophy in school was mostly drudgery for me. But every so often, I would come across a philosopher whose impossibly difficult idea became suddenly illuminated by the clarity of his words.
You may have heard of the highly improbable test of moral philosophy called Trolleyology. This article has a bumpy start, but don't be discouraged, keep reading. By the end, you'll be scratching your head wondering why there is such a big difference between a "flick" and a "shove" when it comes to killing a man.
