However, I was asked to look directly at the subject of teaching, not theoretically, but practically in the context of a large school, with its more or less complicated organization, its daily routine and its daily tasks. I was expected to take a large class of students, meet them regularly on a day-to-day basis and give them systematic courses on the legal branches assigned to me. To achieve this, it was first necessary for the students` efforts to go hand in hand with me, that is, to study in direct relation to my teaching; second, that the much-needed study should be how they could reap the greatest and most lasting benefits; third, that teaching should be so important that students could at least benefit more than spending the same amount of time on private studies. How could this triple object be reached? I saw only one mode that seemed to have a reasonable chance of success; and it was, to make a number of cases, carefully chosen from the books of the reports, the theme of study and teaching. But here I was struck by a practical difficulty apparently insurmountable at first, namely the lack of books; Indeed, while it is possible that private students may have free access to a complete library to transfer them directly to the report books, such a course was not possible with a large class that wants all the same books at the same time. Such a course would also be without major drawbacks and disadvantages, even in the case of a single student. Since he always had to go where the books were and could only have access to them at certain prescribed times, it would be impossible for him to save his time or his work at the best of his own benefit; and he could be constantly persecuted by the fear that he would spend time, work and money studying matters that would not be accessible to him after life. Love and affection are not legitimate forms of consideration. A promise to give a gift does not involve any consideration, as it does not bring any legal benefit to the recipient of the promise or legal prejudice to the promise. Since a promise to make a gift is made freely by the promisor, which is not subject to a legal obligation, the promise is not applicable unless there is Promisesory Estoppel.
