engaged in study; and I have expended much, [in learning,] as others generally do; but yet I am sure that within a quarter of a year, or half a year, I could teach orally, to a man eager and confident to learn, all that I know of the powers of the sciences and languages; provided only that I had previously composed a written compend.  And yet it is known that no one else has worked so hard or on so many sciences and tongues; for men used to wonder formerly that I kept my life on account of my excessive labor, and ever since I have been as studious as I was then, but I have not worked so hard, because, through my practice in knowledge, it was not needful."[16] Again he says, that in the twenty years in which he had specially labored in the study of wisdom, neglecting the notions of the crowd, he had spent more than two thousand pounds [livres] in the acquisition of secret books, and for various experiments, instruments, tables, and other things, as well as in seeking the friendship of learned men, and in instructing assistants in languages, figures, the use of instruments and tables, and many other things.  But yet, though he had examined everything that was necessary for the construction of a preliminary work to serve as a guide to the wisdom of philosophy, though he knew how it was to be done, with what aids, and what were the hindrances to it, still he could not proceed with it, owing to the want of means.  The cost of employing proper persons in the work, the rarity and costliness of books, the expense of instruments and of experiments, the need of infinite parchment and many scribes for rough copies, all put it beyond his power to accomplish.  This was his excuse for the imperfection of the treatise which he had sent to the Pope, and this was a work worthy to be sustained by Papal aid.[17]

The enumeration by Bacon of the trials and difficulties of a scholar’s life at a time when the means of communicating knowledge were difficult, when books were rare and to be obtained only at great cost, when the knowledge of the ancient languages was most imperfect, and many of the most precious works of ancient philosophy were not to be obtained or were to be found only in imperfect and erroneous translations, depicts a condition of things in vivid contrast to the present facilities for the communication and acquisition of learning, and enables us in some degree to estimate the drawbacks under which scholars prosecuted their studies before the invention of printing.  That with such impediments they were able to effect so much is wonderful; and their claim on the gratitude and respect of their successors is heightened by the arduous nature of the difficulties with which they were forced to contend.  The value of their work receives a high estimate, when we consider the scanty means with which it was performed.
