My simple explanation of why we human beings, the most advanced species on earth, cannot find happiness, is this: as we evolve up the ladder of being, we find three things: the first, that the tension between the range of opposites in our lives and society widens dramatically and often painfully as we evolve; the second, that the better informed and more intelligent we are, the more humble we have to become about our ability to live meaningful lives and to change anything, even ourselves; and consequently, thirdly, that the cost of gaining the simplicity the other side of complexity can rise very steeply if we do not align ourselves and our lives well.
