Positive Logic Algebra
To build a virtual condition using input names the boolean operations AND and OR are allowed. The NOT operator is not possible because the input names can not be negated, even when they apparently describe boolean values. They simply exist or not.

Famous quotes containing the words positive, logic and/or algebra:
“As for the terms good and bad, they indicate no positive quality in things regarded in themselves, but are merely modes of thinking, or notions which we form from the comparison of things with one another. Thus one and the same thing can be at the same time good, bad, and indifferent. For instance music is good for him that is melancholy, bad for him who mourns; for him who is deaf, it is neither good nor bad.”
—Baruch (Benedict)
“Though living is a dreadful thing
And a dreadful thing is it
Life the niggard will not thank,
She will not teach who will not sing,
And what serves, on the final bank,
Our logic and our wit?”
—Philip Larkin (1922–1986)
“Poetry has become the higher algebra of metaphors.”
—José Ortega Y Gasset (1883–1955)
