There is a classic episode of Yes Prime Minister (“The Bishop’s Gambit”) in which Jim Hacker has to choose between two problematic candidates for a vacant bishopric. One is a “modernist” and the other is a “separatist” (of church and state). There is a famous exchange that runs as follows: Sir Humphrey : “The Queen is inseparable from the Church of England” Hacker: “What about God?” Sir Humphrey: “I think he’s what is known as an optional extra”. Sir Humphrey explains that a “modernist” is a coded word. “When they stop believing in God they call themselves modernists”. Theists tend to prefer the word “faith” to “belief”. Much blood has been spilled across the centuries over the question of whether the wafer and wine offered as part of holy communion are really the body and blood of Christ or merely symbols. If you think that the answer to that question is obvious (and the chances are 1000-1 on that you do) that is because you can’t help yourself. Belief is not a result of choice. It’s something that happens to you based on the empirical evidence that you see. FAITH IS NOT AN INVESTMENT TOOL By contrast, faith is a great liberator. The more improbable something is, the deeper the faith required to accept it. Faith is not based on reason. Consequently, behaviour driven by extreme faith often looks like irrationality or worse to outsiders. For this reason belief is an essential tool of investment while faith is a menace. It is often difficult to distinguish one’s own beliefs from what might loosely be called wishful thinking. It is quite natural, but not good, to suffer from confirmation bias when hearing news about a company in which one has already taken the decision to invest. Confirmation bias is a symptom of faith. Not merely in investment but in all aspects of life we are keen and competitive to be clever and right and successful. I find it remarkable how hard it can sometimes be to work out what I actually believe. I would like to think that my beliefs frequently coincide with what turns out to be the truth but the relationship between belief...
