Delusional mensapsychosis

Here is another term we need. It refers to a person who receives a high score on an IQ test and so decides there is no longer any reason to think about anything. Any crazy notion this person has must be true because it comes from a clearly superior intellect. There is no need to argue with people who disagree, since it is obvious that they are inferior and simply do not understand.

Fideopsychosis

I have been somewhat reticent to post this, because I am afraid somebody is going to misinterpret what I say and take offense at it. If you are that person, please post here so I can have a chance to respond.

I have long thought that we need a word for the type of insanity that some people demonstrate when they talk about religion. Everybody has probably met somebody who is perfectly reasonable, only to be warned not to talk to that person about religion. If you do engage the person on religion, you find yourself lost in a maelstrom of bizarre ideas and find rational discourse impossible. I don't mean to say that all religious people are insane, only that certain people seem to lose their capacity for rational thought when discussing religious topics.

I know some people will say that these are likely people who have such a sublime understanding of ultimate truths that they cannot communicate them without seeming insane. Perhaps.

The word I propose is "fideopychosis." I will take other suggestions.

Insouciant

This isn’t a big deal, but it is something that I have been wondering about. There are two French words that we use rather frequently in English: “insouciant” and “nonchalant.” It occurred to me that these words mean roughly the same thing. So I looked them up, and sure enough “nonchalant” is given as a synonym of “insouciant.” So my question is, why do the French have two words for an attitude that English-speaking people have not come up with a single word for? I guess “carefree” is kind of close in meaning, but not exactly. Please respond with any thoughts you might have.
