People are saying that they want be convinced [about global warming], perfectly. They want to know the climate science projections with 100 per cent certainty. Well, we know a great deal and even with that there is still uncertainty. But the trend line is very clear. We never have 100 per cent certainty. We never have it. If you wait till you have 100 per cent certainty, something bad is going to happen on the battlefield. That's something we know. You have to act with incomplete information. You have to act based on the trend line.

Philosophy, though unable to tell us with certainty what is the true answer to the doubts which it raises, is able to suggest many possiblities which enlarge our thoughts and free them from the tyranny of custom. Thus, while diminishing our feeling of certainty as to what things are, it greatly increases our knowledge as to what the may be; it removes the somewhat arrogant dogmatism of those who have never travelled into the region of liberating doubt, and it keeps alive our sense of wonder by showing familar things in an unfamilar aspect

The only difference between causation and the value is that the word "cause" implies absolute certainty whereas the implied meaning of "value" is one of preference. In classical science it was supposed that the world always works in terms of absolute certainty and that "cause" is the more appropriate word to describe it. But in modern quantum physics all that is changed. Particles "prefer" to do what they do. An individual particle is not absolutely committed to one predictable behavior. What appears to be an absolute cause is just a very consistent pattern of preferences.

The world’s most famous mathematician was also its first rhetorician.
