In the long run, the public interest depends on private virtue.

The selection process has been powerful enough to produce one indisputable outcome: the family is a universal human institution. . . . In virtually every society into which historians or anthropologists have inquired, one finds people living together on the basis of kinship ties and having responsibility for raising children. . . . Even in societies where men and women have relatively unrestricted sexual access to one another beginning at an early age, marriage is still the basis for family formation. It is desired by the partners and expected by society.

The view that we know less than we thought we knew about how to change the human condition came, in time, to be called neoconservatism. Many ... , myself included, disliked the term because we did not think we were conservative, neo or paleo. (I voted for John Kennedy, Lyndon Johnson and Hubert Humphrey and worked in the latter's presidential campaign.) It would have been better if we had been called policy skeptics; that is, people who thought it was hard, though not impossible, to make useful and important changes in public policy.

Arresting a single drunk or a single vagrant who has harmed no identifiable person seems unjust, and in a sense it is. But failing to do anything about a score of drunks or a hundred vagrants may destroy an entire community.

Police ought to protect communities as well as individuals.... Just as physicians now recognize the importance of fostering health rather than simply treating illness, so the police - and the rest of us - ought to recognize the importance of maintaining, intact, communities without broken windows.
