I agree. Although he should have added.. 'which can lead to discontentment'. The whole notion of 'sameness' is quite boring if one thinks about it. Imagine driving down a street where all the houses and gardens are exactly the same and identical. How... boring. Sure we may feel a sense of contentment, as though we feel at home knowing that all is the same and as it should be. But human beings, or most human beings, do have imagination and even if all were brainwashed into thinking or being the same, at some point or other, there would be that one individual who broke the mould and became different. Imagine a child living in such a street, where everyone and everything is the same. What would this child's imagination be? Would it reflect what was or what could be? That's what it comes down to in the end doesn't it? As Baron pointed out, we all like to imagine 'what could be' and no amount of being the same could breed that out of the human race.
