Imprecision Quotes
Among the various paradigmatic changes in science and mathematics in this century, one such change concerns the concept of uncertainty. In science, this change has been manifested by a gradual transition from the traditional view, which insists that uncertainty is undesirable in science and should be avoided by all possible means, to an alternative view, which is tolerant of uncertainty and insists that science cannot avoid it. According to the traditional view, science should strive for certainty in all its manifestations (precision, specificity, sharpness, consistency, etc.); hence, uncertainty (imprecision, nonspecificity, vagueness, inconsistency, etc.) is regarded as unscientific. According to the alternative (or modem) view, uncertainty is considered essential to science; it is not only an unavoidable plague, but it has, in fact, a great utility.

At the heart of liberty is the right to define one's own concept of existence, of meaning, of the universe, and of the mystery of human life.... people have organized intimate relationships and made choices that define their views of themselves and their places in society, in reliance on the availability of abortion in the event that contraception should fail.... We conclude the line should be drawn at viability, so that, before that time, the woman has a right to choose to terminate her pregnancy.... there is no line other than viability which is more workable. To be sure, as we have said, there may be some medical developments that affect the precise point of viability, but this is an imprecision within tolerable limits.... A husband has no enforceable right to require a wife to advise him before she exercises her personal choices.
