Although it is much more satisfying and stimulating to be guided strictly by interest as one progresses in one’s studies, there is no doubt that sometimes this approach can lead to a feeling of stagnation. This is because, by taking the opposite approach, that is, by conducting a systematic and in-depth study in a specific area of knowledge, progress becomes all too evident. Terminology, once absorbed, becomes commonplace; more and more details are assimilated, in an act that also strengthens the basis of the discipline, which seems to become increasingly obvious. However, on this path, one usually reaches a point where one notices the great distance already accomplished from that initial stimulus that motivated interest. Then, the philosophical impulse, which is essentially synthesizing, complains about the uselessness of specialization and calls for breadth. Thus, the tendency is to adopt the previous stance. Stagnation and uselessness, therefore, are the ghosts that the student must learn to dispel.
