Sicarius, if you read my previous post, I was talking about the prolific presence of super stimulus in the modern world. I mean that it's more pleasurable in the hedonistic measurable sense of the word. The direct reward of your brain's pleasure centres. It's not exactly happiness, but as a measurable quantity, it is definitely greater now than before. I was saying that contrary to spyman's claim that primitivists feel that we are less happy now, I was saying that no, I think many of them are reacting negatively to the massive indulgence around them, and that rather, people might be too "happy".
As to my example, see Dan Gilbert.

Concerning a rate of unnatural extinction... my point was that any level that you pick is arbitrary. At what point is it acceptable or unacceptable? You can say in a vague sense that the current rate is unacceptable, and that the primitive rate is acceptable, but where along the way does that change? Does it magically happen at the dawn of agriculture, perhaps the Middle Ages, perhaps the Industrial Revolution? Maybe we haven't actually hit that unacceptable rate yet... I'm not saying we shouldn't be environmentally conscious and try to reduce the rate of extinctions... what I am saying is that the fact that humans cause extinctions is no argument for primitivism versus the modern world. It's a valid point, but not for that argument.
