A lesson

The master entered in the room while the students spoke one other around the philosophical arguments that the day before the master has treated, and when they gave the attention to master somebody asked: “What is syllogism master?”, the master looked around and took and chair he begun the lesson: “The proposition is affirmative discourse or negative around something. It is or universal or particular or indefinite. I call universal that is belong to everything or nothing; particular belong to something, indefinite belong or not without indication of universal or particular, but belong and stop: for example, to identic the science of contraries…”, the student interrupted soon and asked: “What is mean of this affirmation? Because I and think we haven’t understood it”, the master smiled and: “Normal, without explication it is very easy but I must go you to think no one but two particulars. To understand one quality and have a deep acknowledge of one quality, we must know also his contrary, one example: for love the air that we breath always, and that to us now is normal, we must lack of this vital element to life, we can immerse the head in a bathtub, and after some second and after up the head, the air is going to be important and it is very pleasure; hence you have known the lack of air and you have known the danger of suffocation, thereupon you, after left danger you love the air, certainly very scan because you retake you natural habit as the breath, but some moment, after the danger you appreciate the air; whereby you must know the contrary of natural to appreciate the natural.”. Other student, exited curiosity, asked: “The difference of proposition?”, and master: “Yes very good question: the difference is so: the demonstrative proposition differs from that dialectical, because the demonstrative is assumption of one alone of two parts of contradiction, for example you want affirm that the sky is blue, and if somebody want demonstrate the contrary you very easily indicate the sky, this is right?”, and student: “Yes”, and master following: “But you has took alone the affirmative part of this proposition”, and student: “Because it is normal, the sky is blue and it is evident, thereupon it is undeniable”, and the master: “Certainly but now, and this night the sky is going to be blue?”, and the student: “No! During night can’t be”, and the master: “But you have took alone a part of proportion, that is affirmative, that the sky now is blue, and haven’t other, it is demonstration that you can affirm the reality taking alone a part of proposition; and who want demonstrate something doesn’t give question, but take that is necessary to demonstration of his thesis; the dialectical is question of a contradiction; in fact I have contradicted your affirmation, because I have said other truth, this is the this night sky is going to be not sky, this is dialectical proposition that want the affirmative and negative proposition” Other student said: “But you haven’t explained what works the syllogism”, and master gazed him and answer: “I am here: a proposition of syllogism, in absolute sense is affirmation of negation of something regard something, instead it is demonstrative if it is true; dialectical to whom asks, interrogation of a contradiction. The syllogism is a discourse, that set something, other is necessarily following from that is set since that exist, the explication of this concept: since these thing exist the derivation from these, and I say derived from these, this is not need nothing word to have that is necessary”, students were astonished because they didn’t understand the meaning of this affirmation, whereby the master: “I understand that to you it is difficult, because I have explain it with philosophical sense, but we can very easily: we must consider the logic existence of something, and we can set it syllogism, common objects that are in our life, and since these objects are present we can use to our logic think. The logic discourse is very easy to understand for this we must consider the common logic: if nothing pleasure is a good, neither good is a pleasure. It is elementary logic ands stop”; after given these explication he glazed the door and gone to exit of room, and a student asked: “Where are you going?”, and he turned toward the student and answered: “My father, Nicodemus is died in Macedonia, where is the son of Philip king that needs of a tutor”, and he exited from the room.
