Logic science according to high school curricula

And after, this is the student's book according to the modern curriculum in logic, which called us to put it in service of the sons of the homeland, and to clarify the correct purposes of the topics of this curriculum that some of the brothers were blind to either because of its difficulty or because they were not present in the circulated books. And we do not claim favor over them; because the credit for this goes back to the happy opportunity that allowed one of us to be a member of the committee that prepared it, fully aware of what is required of it, and the other to teach this subject for a few years. And we summarized in the statement without neglecting the rulings, and we followed each chapter with exercises that reinforce it in the minds. If we have succeeded in what we aimed for, that is by the grace of God upon us.
