Give us this day our daily mask. - Tom Stoppard

It is a defect of God's humour that he directs our hearts everywhere but to those who have a right to them.

When someone disagrees with you on a moral point you assume that he is one step behind in his thinking, and he assumes that he has gone one step ahead. But I take both parts, O'Hara, leapfrogging myself along the great moral issues, refuting myself and rebutting the refutation towards a truth that must be the compound of two opposite half-truths. And you never reach it because there is always something more to say.

Real data is messy. ...It's all very noisy out there. Very hard to spot the tune. Like a piano in the next room, it's playing your song, but unfortunately it's out of whack, some of the strings are missing, and the pianist is tone deaf and drunk- I mean, the noise! Impossible!
