“The power of the good is enormous, but depends on its consistency. That is why the good has to be an issue of “all or nothing,” “black or white,” and why evil has to be partial, occasional, “gray.” To be evil “only sometimes” is to be evil. To be good is to be good all of the time, i.e., as a matter of consistent, unbreached principle.”
— Leonard Peikoff, “O.P.A.R.”, page 266.
In another life, I worked a bit with Fuzzy Logic, and I used to say that “life is fuzzy, but I am boolean” when talking about integrity. It is a hard, not always successful way of living, but the only one that allows me to sleep at night.

Integrity is loyalty in action to one’s convictions and values. As Ayn Rand put it, the man of integrity may “permit no breach between body and mind, between action and thought, between his life and his convictions….” But to keep all your value-judgments ready at hand amid the turbulence of everyday life is a volitional task. And a hard one. You need to hold the full context of your knowledge in focus while retaining your long-range purposes in front of your eyes all the time. The only way you can do that is if you have integrated your knowledge and purposes into principles.
