Statement that goes beyond such evidence as
one has; statement to the effect that everything, within or without particular
evidence, is such-and-such.
One may generalize for many reasons, good or bad, but any
empirical test of any theory involves some generalization, namely - at least -
that the theory also concerns future observations that have not been made yet.
A common usage of "generalization" that is not quite conforming to the
above is that of "existential
generalization", which concerns that "there is an x which is F" or "some x
are F" from "a is F", although it is true that the existential generalization
is less definite and so more comprehensive than what it generalizes from.
