After having read a lot of fiction, literature, whatever you want to call it, from Wolfe to Houellebecq, I think you have to have an understanding and insight of the human condition that is informed and motivated by a desire to immerse yourself in the human world and bring these stories to bear.
My understanding of first-degree murder is that premeditation needs to be proven.
An appreciation of animals is good for a human, it can lead to a better understanding and respect for all living things.
Nietzsche, who you don't spend too much time with after the age of seventeen, did have that one great line about "he who stares into the abyss must know that the abyss also stares into him" and I never really understood that until my friend got killed and you really get your head around the idea of what horror means. It's a truly awful thing, to really, kind of have that understanding of things and when you really peer into that.
