Abstract
Let U be any complete lattice. Then, as observed in Chapter 4, in fuzzy logic it would be misleading to consider an initial valuation v: F→ U as a fuzzy subset of F As a matter of fact, for any formula α, the number v(α) is not the truth value of α but a constraint on its actual truth value, namely a constraint like
“the truth value of a is greater than or equal to v(α)”.
