Future generations may or may not judge Wittgenstein to be one of the great philosophers. Even if they do not, however, he is sure always to count as one of the great personalities of philosophy. From our perspective it is easy to mistake one for the other; which he is time will tell.

I believe that decisions about the timing and manner of death belong to the individual as a human right. I believe it is wrong to withhold medical methods of terminating life painlessly and swiftly when an individual has a rational and clear-minded sustained wish to end his or her life.

It takes a certain ingenuous faith - but I have it - to believe that people who read and reflect more likely than not come to judge things with liberality and truth.

And I say, the meaning of life is what you make it. There will be as many different meaningful lives as there are people to live them.

Science is the outcome of being prepared to live without certainty and therefore a mark of maturity. It embraces doubt and loose ends.

Perhaps worse still is what liberal societies might do to themselves in the face of this new and different threat [of terrorism]. They begin, by small but dangerous increments, to cease to be as liberal as they once were. They begin to restrict their own hard-won rights and freedoms as a protection against the crminial minority who attempt (and as we thus see, by forcing liberty to commit suidcide, succed in doing) to terrorise society.

Religious apologists complain bitterly that atheists and secularists are aggressive and hostile in their criticism of them. I always say: look, when you guys were in charge, you didn't argue with us, you just burnt us at the stake. Now what we're doing is, we're presenting you with some arguments and some challenging questions, and you complain.
