 Although delusions can be irrational to a higher degree than normal beliefs, as they may be less consistent with our other beliefs and behavior and more resistant to counterevidence, they do not seem to be irrational in a qualitatively different way from nondelusional beliefs. This would suggest that there are elements of continuity between delusions and irrational beliefs, although (as we shall see in the next section) there exist sophisticated philosophical arguments challenging the continuity claim.
