People would tell me: "Now is the time for you to study; later on, you will have leisure to enjoy yourself; and after that will come the time to make money." But I needed all three times in which to do nothing--and I could have used another three hundred. PROFESSORS I have not been fortunate in my professors. It might be urged that I have not been in a position, being idle and sluggish, to take advantage of their instruction. I believe, however, that if they had been good teachers, now that so many years have passed, I should be able to acknowledge their merits. I cannot remember a single teacher who knew how to teach, or who succeeded in arousing any interest in what he taught, or who had any comprehension of the student mentality. No one learned how to reason in the schools of my youth, nor mastered any theory, nor acquired a practical knowledge of anything. In other words, we learned nothing. In medicine, the professors adhered to a system that was the most foolish imaginable. In the two universities in which I studied, subjects might be taken only by halves, which would have been ridiculous enough in any branch, but it was even more preposterous in medicine. Thus, in pathology, a certain number of intending physicians studied the subject of infection, while others studied nervous disorders, and yet others the diseases of the respiratory organs. Nobody studied all three. A plan of this sort could only have been conceived by Spanish professors, who, it may be said in general, are the quintessence of vacuity. "What difference does it make whether the students learn anything or not?" every Spanish professor asks himself continually. Unamuno says, apropos of the backwardness of Spaniards in the field of invention: "Other nations can do the inventing." In other words, let foreigners build up the sciences, so that we may take advantage of them. There was one among my professors who considered himself a born teacher and, moreover, a man of genius, and he was Letamendi. I made clear in my _Tree of Knowledge_ what I thought of this professor, who was not destitute, indeed, of a certain talent as an orator and man of letters. When he wrote, he was rococo, like so many Catalans. Sometimes he would discourse upon art, especially upon painting, in the class-room, but the ideas he entertained were preposterous. I recall that he once said that a mouse and a book were not a fit subject for a painting, but if you were to write the words _Aristotle's Works_ on the book, and then set the mouse to gnawing at it, what had originally meant nothing would immediately become a subject for a picture. Yes, a picture to be hawked at the street fairs! Letamendi was prolixity and puerile ingenuity personified. Yet Letamendi was no different from all other Spaniards of his day, including even the most celebrated, such as Castelar, Echegaray and Valera.
