With permission of Fede, which will soon be the champion of our dictionary and I think that it is civilian mine in Hinojosa de Duero in Salamanca, cAmEnEs or CAmElEs is a mnemonic in a valid way, how very well said, the 4th figure. In Aristotelian logic mode tells us how are the proposals of the syllogism: here the first is ( AT ) Universal affirmative, the second is ( E ) Universal negative and the conclusion ( E ) Universal negative. Figure determines the distribution of the terms ( subject, predicate, term average ) in the syllogism. In the 4th figure the average made predicate the greater or first premise and subject in the youngest or second premise. An example of camenes: every man is vertebrate; No vertebrate is unicellular; no single-celled beings then is man.
