Sure. "Logic" just means a system of rules by which a proposition may be stated, described, derived, proven, determined to belong to one or another classification, etc. You could have a system that divides all possible statements into classes "T" or "F" or you could have a system under which there are more than two classes.
The classes don't necessarily need to correspond to everyday notions of reality, but if you do wan them to map, you could imagine diving statements into those that are true, false, unknown, unknowable, nonsensical, probabalistic, and so on.
A common-sense example would be a system that evaluates the satement "it will be 72 degrees tomorrow."
That is neither true nor false. It is unknown. It may be likely, it may be unlikey. Or the answer could be that the statement makes no sense because it doesn't ask when it will be 72 degrees, or where. Or when tomorrow is -- is that statement's truth supposed to be evaluated as of the time it's posted on Yahoo, or as of the time it's read?

In harmony with Monso Ordas answer: Is that what people are defining as 'value' when using words 'true' and 'false'? When a logic becomes in human mental function, as 'is', is 'as' itself or other. Why not a four 'value' system? contradiction to known true is zero, contradiction to known true with differential condition added is one, contradiction to unconfirmed description 2, confirmed true is three, i.e. testing for exception, when, not when, where, not where, with what, not with what, with who, not with who, how, other how....
Binary electronic logic coding system/process: high voltage 5.4, low voltage 0.6, 1, 0, 2 bit, 4 bit, 8 bit, 16 bit, 32 bit....trinary, high voltage 12, medium voltage 6, low voltage 0.6, 2, 1, 0, 3 bit, 6 bit, 12 bit, 24 bit ....
1000 voltage differentials to an 8 bit count for byte definer one thousand to the exponential power of 8 possible symbols for one byte symbol length or 1000,000,000,000,000,000,000,000 single character symbols.

Yeah, check out quantum computing.
Or even better, check out fuzzy logic. It varies from 0 to 1 using real numbers and there are logical operators defined for them, and fuzzy logic is used today for all kinds of consumer gadgets like thermostats, washing machines, etc. to capture concepts of partialness or fuzziness which we find in the real world, rather than the black and white of the pure dialectic logical world.

Yep. There are multiple three valued logic propositions.
Unknown and Maybe are two.

Yah, I think the other other possibility could be W for what the hell.

There is; it's called "gray".
True and false, like right and wrong, is about perspective. If one has more than one perspective on an issue, then it is a gray.
