Can you name a major issue on which you've changed your mind?
... the one that required the most agonizing - was realizing that 'anti-imperialism' (or 'opposition on principle to Western military intervention') was something highly negative and reactionary, rather than positive and progressive.
What philosophical thesis is it most important to combat?
The misguided belief that true morality lies in attachment to a set of dogmas - be they religious, political or other - and that these dogmas must be rigidly adhered to, by ignoring evidence that undermines them or changes in the world that render them obsolete, and by suppressing one's own sense of scepticism.
What philosophical thesis is it most important to disseminate?
That positive principles, goals, societies and individuals should continually grow, evolve and be reinvented, while those that remain rigid and unchanging will stagnate and cease to be positive.
... There's a price to be paid for human progress, but that doesn't mean one should look back nostalgically to a mythical 'golden age'.
