[E]quality is not the empirical claim that all groups of humans are interchangeable; it is the moral principle that individuals should not be judged or constrained by the average properties of their group. ... If we recognize this principle, no one has to spin myths about the indistinguishability of the sexes to justify equality.

Increasingly, politics is not about "who gets what, when, how" but about values, each of them considered to be absolute. Politics is about "the right to life"...It is about the environment. It is about gaining equality for groups alleged to be oppressed...None of these issues is economic. All are fundamentally moral.
Peter Drucker
The simple point which I am concerned to make is that where ultimate values are irreconcilable, clear-cut solutions cannot, in principle, be found. To decide rationally in such situations is to decide in the light of general ideals, the overall pattern of life pursued by a man or a group or a society.

It's not even probable, let alone scientifically proven, that HIV causes AIDS. If there is evidence that HIV causes AIDS, there should be scientific documents which either singly or collectively demonstrate that fact, at least with a high probability. There are no such documents. Spin Magazine, Vol. 10 No.4, 1994.
Kary Mullis
And a third danger is timidity. Few men are willing to brave the disapproval of their fellows, the censure of their colleagues, the wrath of their society. Moral courage is a rarer commodity than bravery in battle or great intelligence. Yet it is the one essential, vital quality of those who seek to change a world which yields most painfully to change.
Robert F. Kennedy
Theory should be ever more demanding of our empirical resources. Simultaneously, data should be ever more demanding of the empirical relevance of theory and of the theorist's expertise in working imaginatively on problems of the world, rather than on stylized problems of the imagination.
