Is sanity rational?

[bennyboy]

It would seem like an appropriate time for Insanity to make his way back to the forums and give us his perspective on the OP.

As for mine, sanity is measured by the degree of congruity and internal consistency that exists between a thought, statement, or behavior and the object it claims to represent or the goal it seeks to attain. As for congruity to an object, we have successful and proven methods for determining as much; as for congruity to a goal, present consensus within society is the ultimate judge.

Okay, so what's the congruity between "I am extremely important, and must be protected, respected and valued" and "The universe consists of trillions of stars and billions of galaxies. One of the stars has a little watery rock orbiting it, and on this rock are trillions of living things, of which I am one."

Is feeling that one is important sane?
