Not to be confused with Lambda cube.

In the system of Aristotelian logic, the logical cube is a diagram representing the different ways in which each of the eight propositions of the system is logically related ('opposed') to each of the others.[1] The system is also useful in the analysis of syllogistic logic, serving to identify the allowed logical conversions from one type to another.[2]
