I received no reply until the beginning of 1663, my correspondent’s laxity and the winter posts both conspiring to cause delay. Even then, his response produced little of interest and, lest anybody think I was careless, I append here Mr. Jackson’s letter:

The letter then concluded with hopeful remarks saying that if I wanted to acquire any paintings, Thomas Jackson Esquire (not that he had any right to call himself such, being a mere painter) would be most grateful for the privilege of obliging.

When I received this letter, I naturally wrote to Mr. Bennet about this man Giovanni di Pietro—if the Venetians did have a correspondent in London, I felt the government should know who he was. Somewhat to my surprise, I received a curt note back—This di Pietro was already known to them, was of no danger to the government and Mr. Bennet was sure I had much more profitable areas of enquiry. He reminded me that my task was the repression of sectaries; other questions were none of my concern.

I was too occupied to be other than thankful for this as there were definite signs that the sectaries were indeed rumbling again and I had more than enough to keep me busy. Reports reached me of consignments of arms flitting about the country, of little conventicles of radicals meeting, then dispersing. Most dangerous of all, a solid report came that Edmund Ludlow, the most dangerous and able of the old generals still at liberty, had been receiving an unusually large number of visitors in his exile in Switzerland. The beast was stirring, but still it was like trying to measure the waters in the hollow of your hand (Isaiah 40:12). In several parts of the country I knew that trouble was brewing—I did not know why, or who was behind it all.

It should not be thought that my activities took place only in Oxford—I was, naturally, bound to be there during some of the term but much of the year I was at liberty, and spent a good part of my time in London, for not only did this give me access to the Secretary of State (Mr. Bennet received his reward that November), much of learned society was migrating there as well and I naturally wished to spend time in their company. The great venture of the Royal Society was under way, and it was vital that it was constructed along good lines, only admitting proper people and keeping out those who wished to pervert it to ungodly ends—papists at one extreme, atheists at the other.

Shortly after a meeting of the Society, Matthew, my servant, though far more than that, came to me. I will dwell much on this young man in my narrative, for he was as dear to me as a son; dearer, in fact. When I consider my own sons, doltish buffoons with whom no man of sense can converse, I despair of my misfortune. “A foolish son is the calamity of his father” (Proverbs 19:13); how much have I meditated on the truth of this saying, for I have two such fools. I tried once to teach the elder the secrets of decipherment, but might as well have attempted to instruct a baboon in the theories of Mr. Newton. They were left to my wife when young, since I was too busy on government business and in the university to attend to them, and she brought them up in her image. She is a good woman, everything a wife should be, and brought me an estate, yet I wish I had never been constrained to marry. The services a woman provides in no manner compensate for the inadequacy of her company, and the liberties she curtails.

I have been greatly occupied at times of my life with the problems of educating the young; I have worked on the most unpromising material, persuading the dumb to speak and trying, from that, to arrive at general principles about the malleability of the infant mind. I would have young boys entirely removed from the company of women, especially that of their mothers, from about the age of six so that their minds might be occupied with lofty conversation and noble ideas. Their reading, their education and even their play should be directed by a man of sense—and by that I do not mean those wretches who habitually pass themselves off as schoolteachers—so that they might be excited to emulate what is great, and shun what is ignoble.

Had a boy such as Matthew come into my company but a few years earlier, then I believe I could have made a great man of him. The moment I saw him, I was struck with an inexpressible regret, for in his carriage and in his eyes I saw the son and companion I had prayed God to give me. Scarcely educated, and even less well trained, he was more a man than those children of mine who had every care expended on their puny minds, and whose ambition nonetheless extended no further than a desire to secure their own comfort. Matthew was tall and fair, and had such an expression of the most perfect compliance in his manner that he compelled the favor of all who encountered him.

I first met him when he was questioned by Thurloe’s office about a group thought to be too radical for the country’s peace; he was perhaps sixteen at the time. I merely attended, rather than conducted the interview (a business for which I never had much patience) and was immediately struck by the forthright honesty in his responses, which showed a maturity beyond both his station and years. He was, in fact, entirely innocent of any wrongdoing and was never suspected of such; but he was acquainted with many dangerous people, even though he did not share their opinions in any way. He was reluctant to give information about his friends and I found this innate sense of loyalty an admirable trait and thought that, could it but be redirected to more worthy ends, this ignorant child might yet be turned into a man of worth.

His interrogation was kept secret lest he lose credit with his friends, and I offered afterward to engage him as a servant at a decent wage; he was so astonished by his good fortune that he accepted with alacrity. Already he had some small learning, for he was the orphan of a printer in the city, and could read well and write with accuracy. And as I tempted him with knowledge, he responded with an enthusiasm I have never met, before or since, in any pupil.

Those who know me may find this incredible, for I know I have a reputation for impatience. I willingly admit that my tolerance for the idle, the stupid or the willfully ignorant is swiftly exhausted. But give me a real pupil, one burning with the desire to learn, who needs only a touch of sweet water to yearn for the whole river of knowledge, and my care is all but infinite. To take such a boy as Matthew, to form him and see his comprehension expand and his wisdom develop, is the richest of experiences, if also the most difficult and calling for unrelenting effort. The getting of children is the vulgar work of nature; fools can do it, peasants can do it and women can do it. Framing those moving lumps into wise and good adults is a task fit only for men and only they can properly savor the result.

“Train up a child in the way he should go—and when he is old, he will not depart from it”(Proverbs 22:6). I had no extravagant hopes but I thought that, in time, I would establish him in some position in the government and ultimately teach him my skills in cryptography, that he might be useful and make his way to position. My hopes were more than satisfied, for however fast Matthew learned, yet I knew he could go faster. But I confess this merely excited my own desires for him still further and I often lost my temper when he misconstrued a phrase, or bungled a simple proposition in mathematics. But I always thought that he knew my anger came from love and selfless ambition for him, and he seemed to try at all times to earn my approbation.
