In his book Varieties of Religious Experience, William James wrote about the power the irrational holds over the rational:
If you have intuitions at all, they come from a deeper level of your nature than the loquacious level which rationalism inhabits. Your whole subconscious life, your impulses, your faiths, your needs, your divinations, have prepared the premises, of which your consciousness now feels the weight of the result; and something in you absolutely knows that that result must be truer than any logic-chopping rationalistic talk, however clever, that may contradict it.
So what do you do as a rational, intellectual person who is fighting a group that is in the grips of their intuition? How do you combat the power that holds? It doesn’t make sense to right the irrational with the rational. You can explain to, say, a Trump supporter very coolly that his economic policy would have disastrous ramifications, or that his foreign policy approach could very well lead us into decades of conflict, but if he’s caught up in a nationalistic fever, especially one that is being used to shore up a fractured sense of self, you will only antagonize and never sway.
