I do not myself think that the dependence of morals upon religion is nearly as close as religious people believe it to be. I even think that some very important virtues are more likely to be found among those who reject religious dogmas than among those who accept them. I think this applies especially to the virtue of truthfulness or intellectual integrity. I mean by intellectual integrity the habit of deciding vexed questions in accordance with the evidence, or of leaving them undecided where the evidence is inconclusive. This virtue, although it is underestimated by almost all adherents of any system of dogma, is to my mind of the very greatest social importance and far more likely to benefit the world than Christianity or any other system of organized beliefs.
