We often have irrational beliefs which are not coherent with the others. If they could be explained under "The Principle of Charity", they would no longer be regarded as irrational. How can we explain irrational beliefs as such and give their place in the system of our beliefs? Donald Davidson proposed "the partitioning of mind" as the answer to this question, but his solution is hopeless because it seems to be inconsistent with holism. I propose the idea of Motivated Irrationality as an explanatory strategy of irrationality, because I think it can explain irrationality more simply than the mental partitioning and give the way out of the paradox of irrationality.
