Of course my statement about standards in a hundred years time is speculation, but it is a reasonable assumption. Society's standards are constantly evolving - they have changed considerably over my own lifetime. To give but one example, attitudes to homosexuality are now completely different from when I was young. It is reasonable to assume that this evolution will continue, in fact it would more be remarkable if it did not. I am warning against the assumption that we are more virtuous than previous generations, when in many cases all that means is that our priorities are different from theirs.
