Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. - Douglas Hofstadter

It now becomes clear that consistency is not a property of a formal system per se, but depends on the interpretation which is proposed for it. By the same token, inconsistency is not an intrinsic property of any formal system.

"It seems to me, therefore, that the instinctive although seldom articulated purpose of holding a funeral or memorial service is to reunite the people most intimate with the deceased, and to collectively rekindle in them all, for one last time, the special living flame that represents the essence of that beloved person, profiting directly or indirectly from the presence of one another, feeling the presence of that person in the brains that remain, and thus solidifying to the maximal extent possible those secondary personal gemmae that remain aflicker in all these different brains. Though the primary brain has been eclipsed, there is, in those who remain and who are gathered to remember and reactivate the spirit of the departed, a collective corona that still glows. This is what human love means. The word "love" cannot, thus, be separated from the word "I"; the more deeply rooted the symbol for someone inside you, the greater the love, the brighter the light that remains behind."

Categorization thus helps one to draw conclusions and to guess about how a situation is likely to evolve.
