Do We Need Fuzzy Logic In Our Databases?

I was reading in Bart Kosko’s book: Fuzzy Thinking, where he mentioned that in much of our science, math, logic, and culture, we have assumed a world of blacks and whites that doesn’t change. In other words, everything is either true or false. Even our computers are based on this concept of black and white, especially when we notice how it is based on the binary strings of 0s (black) and 1s (white).
