Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits—a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities.

For although it is certainly true that quantitative measurements are of great importance, it is a grave error to suppose that the whole of experimental physics can be brought under this heading. We can start measuring only when we know what to measure: qualitative observation has to precede quantitative measurement, and by making experimental arrangements for quantitative measurements we may even eliminate the possibility of new phenomena appearing.
Hendrik Casimir
Statistics are the triumph of the quantitative method, and the quantitative method is the victory of sterility and death.
Hilaire Belloc
...they have brainwashed us into believing in the last 150 years... that quantitative change is superior to qualitative attributes. If we can turn out more... it doesn't matter if they're half as good. ...We're quantifying everything, and that is why we're trying to put everything on computers. Governments will no longer have to make decisions; computers will do it.
Carroll Quigley
All relations are either qualitative or quantitative. Qualitative relations can be considered by themselves without regard to quantity. The algebra of such enquiries may be called logical algebra, of which a fine example is given by Boole.
Quantitative relations may also be considered by themselves without regard to quality. They belong to arithmetic, and the corresponding algebra is the common or arithmetical algebra.
In all other algebras both relations must be combined, and the algebra must conform to the character of the relations.Benjamin Peirce
War is not the answer. Communism will never be defeated by the use of atomic bombs or nuclear weapons. Let us not join those who shout war and, through their misguided passions, urge the United States to relinquish its participation in the United Nations. These are days which demand wise restraint and calm reasonableness. We must not engage in a negative anticommunism, but rather in a positive thrust for democracy, realizing that our greatest defense against communism is to take offensive action in behalf of justice. We must with positive action seek to remove those conditions of poverty, insecurity, and injustice, which are the fertile soil in which the seed of communism grows and develops.
