The etymology of apodicticity is Greek. Derives from the verb apodeiknimi: do see, proclaim, demonstrate, test and means " what is demonstrably ": what can show in a clear way as true or false. Thus the Greek philosopher understood what Aristotle in the fourth century a. d. C.. Kant, philosopher illustrated of the 18th century, understood it as logically necessary and therefore necessarily true.
The German philosopher Enmanuel Kant, in the 18th century, in his "Critique of pure reason " It makes a very critical of human knowledge and mode analysis as we know through concepts, judgements and reasonings. It is classified according to the quantity, quality and value judgements.

The trial asertoricos that are those who express a real fact: Madrid is the capital of Spain. and finally the apodictic judgments that are those who express a logical necessity as " two and two are four ".
