Do you live your life by your principles?

No, absolutely not. In fact that is *all *you can do. I (and Tynan too apparently) just have no truck with the idea that living by one's principals will make any difference as regards the future of our species. It's a comforting delusion at best. That is not at all the same as believing one has carte blanche to be a bastard.
And that rat you smell is, funnily enough, one of the few mammals that will be around long after we are gone.

Yes, all that.

"It's a comforting delusion at best." - and at worst (which I insist is the fact of it) it is - as I have said before - actually worsening the problem (or better said: obscuring the problem so that it can be more easily ignored).

I have just got two cans on Becks.
