““Cultural pessimism is always fashionable, and since we are human, there are always grounds for it. It has the negative consequence of depressing the level of aspiration, the sense of the possible... it is easy to forget that there are always as good grounds for optimism as for pessimism--exactly the same grounds, in fact--that is, because we are human. We still have every potential for good we have ever had, and the same presumptive claim to respect, our own respect and one another's. We are still creatures of singular interest and value, agile of soul as we have always been and as we will continue to be even despite our errors and depredations, for as long as we abide on this earth.””
