The philosopher William Kingdon Clifford argued, that to believe anything because it comforts you, or makes you feel good, or sustains you in life, or makes life a little less intolerable, is not just epistemically wrong, not just intellectually wrong, but morally wrong. In fact, if the decision that needs to be made is serious enough, such as whether or not to send people to war, or whether or not to cut health benefits to millions of people to raise money to give tax breaks to wealthy people, or whether or not to encourage  vaccines to fight serious diseases or encourage eating wild flowers instead, the decision could amount to one of the worst crimes that you can commit. That’s a pretty drastic statement. According to Clifford  It is a travesty and has some horrible consequences.  We will get to those later. In any event, according to Clifford this is a morally wrong. I think it is hard to argue with that. Serious decisions must be made on the basis of serious evidence, analysis, and scrutiny before they are made and innocent people suffer.

Arthur Schafer, a wonderful philosopher and ethicist from the University of Manitoba, and the first philosopher I ever heard speak in person, is a fan of Clifford’s reasoning. According to Schafer, Clifford sees our reliance   on illusion on false pictures of the universe, as amounting to creating in us a walking time bomb. As Schafer said at talk to a talk given to the Winnipeg Humanists, Atheists, and Skeptics, Society,  “to put it a little less dramatically, when we believe things because they make us feel good, rather than because we have good evidence for them, as Clifford argues, we make ourselves credulous people.” That Clifford says is wicked. Schafer agrees with that conclusion. So do I.

Again, we are talking only about serious important issues here. We are not talking about a decision to pick a red jelly bean rather than a white jelly bean from a cup. For those decisions we are completely free to make them on the basis of a whim, or an inkling, or an instinct or even on a guess.  But we can’t justify decisions that seriously affect the health or welfare of other people on such a basis.

If we are credulous people we can easily believe, as the Mennonite woman interviewed by the CBC radio did, that eating wild flowers to combat measles is better than taking vaccines. If we have been conditioned by our parents to be credulous, they are partly responsible. Credulity can be dangerous—to ourselves and others. That is why Clifford and Schafer said encouraging credulity is dangerous for society. Not just for the believer, for society.

We can believe whatever we want but we should be careful about helping to create a credulous society. As we are now seeing everywhere, that can cause a lot of harm.
