John Keighley was a man of considerable property, and at his death, which occurred when Priestley was about twelve years of age, the widow was left with the greater part of his fortune for life, and much of it at her disposal after her death.

By Mrs Keighley’s direction he was sent, he tells us, to several schools in the neighbourhood, especially to a large free school under the care of a clergyman, Mr Hague, under whom, at the age of twelve or thirteen, he first began to make progress in Latin and acquired the elements of Greek. His brother Timothy records that “from eleven to about thirteen he had read most of Mr Bunyan’s works and other authors on religion, besides the common Latin authors.”

How a well-ordered school was conducted in the middle of the eighteenth century may be gleaned from the following regulations in force in Mr Canton’s well-known academy in 1745:—

1. That the School hours are from 7 o’clock in the morning till 12, and from 2 to 5 in the afternoon: except the winter half-year, when they begin at 8 in the morning.

2. That all the Scholars come decently, that is, with their Hands and Faces wash’d, their Hair or Perriwigs Comb’d, and their Shoes black’d.

3. That they bow at Coming in and going out, and when any Thing is given or rec’d; and never wear their Hats in the House or School.

4. That they loiter not, but go immediately to their own seats and move not thence, without Leave, till School is done.

5. That if any Person come into the School whom they know, they are to get up, make a bow, and sit down in their places again.

6. That if the Master be discoursing with, or reading to any Person, they shall not stare Confidently on them or hearken to their Talk, unless required to be present.

7. That they shall not interrupt the Master while a Stranger is talking with him, with any Question, request, or complaint whatsoever, but stay till he is at Leisure.

8. That they shall not presume to talk loud nor make any noise in getting their lessons. A Boy’s Tongue should never be heard, but in saying his Lesson, asking or Answering a Question.

9. That there be no buying, selling, changing, laying Wagers or Gaming in School-time, on the forfeiture of the whole so bought or sold, etc.

10. That those who learn French shall not speak English to any that learn French, on the Forfeiture of ye Bill, or one Hour’s Exercize after School Time.

11. That such as learn Latin are also oblig’d not to speak other Language to those that learn it, during School time, on the Penalty last mentioned.

12. That all perform their Lessons and Exercises in fair Writing and true Spelling, and likewise prepare themselves for their Examinations in French, Latin, Accounts and Catechisms every week, both in School times and all Vacations.

13. That such as perform well, shall be prefer’d according to their Merit, and shall have liberty to leave School before the usual Time; but such as are Negligent herein, shall have their Exercizes to write over again after School.

14. That none presume to call any Party or Nick-names nor give any ill or reproachful Language, much less Curse, Sware, or Lye, but in all things behave in a quiet, peaceable, and civil manner.

15. That the Boarders shall not go beyond ye bounds belonging to ye House on any pretence whatsoever without leave, on the forfeiture of 6d. or two Hours’ Exercize after School for Every such Offence.

16. That one Scholar is not to strike another, or challenge him to fight; but in case of any Difference shall acquaint the Master therewith and be satisfied with his Determination.

Whilst acquiring Greek at the public school, Priestley learned Hebrew on holidays of the Dissenting minister of the place, Mr Kirkby, under whose care he eventually came.

The weakly, consumptive habit into which he now fell necessitated his withdrawal from school. His fondness for books had led his aunt to encourage the hope that he might be trained for the ministry, and he readily entered into her views.

“But,” he says, “my ill health obliged me to turn my thoughts another way, and, with a view to trade, I learned the modern languages, French, Italian and High Dutch [German], without a master; and in the first and last of them I translated and wrote letters for an uncle of mine who was a merchant, and who intended to put me into a counting-house in Lisbon.”

Indeed, he says a house was actually engaged to receive him there, and everything was nearly ready for his undertaking the voyage when his health so far improved that the idea of the ministry was resumed. During the two years in which he had been kept away from school the boy was thrown almost entirely upon his own resources. It says much for the activity and eagerness of his mind, his diligence and his power of mental acquisitiveness, that he should have neglected no opportunity of gaining knowledge from the various heretical divines who came to drink a dish of tea with his aunt. He tells us that from Mr Haggerstone, a Dissenting minister in the neighbourhood, who had been educated under Maclaurin, and whom he visited twice a week, he learned geometry, algebra and various branches of mathematics, theoretical and practical. He also read, with but little assistance from him, Gravesend’s Elements of Natural Philosophy, Watts’s Logic, and Locke’s Essay on the Human Understanding. “He also gave lessons in Hebrew to a Baptist minister at Gildersome, a village about four miles from Leeds, and by that means made himself ‘a considerable proficient in that language.’” “At the same time I learned Chaldee and Syriac, and just began to read Arabic.”

As his knowledge increased, and the powers of his intellect strengthened, he began to exercise his reason upon the many problems of doctrine and religious belief which could not fail to be uppermost in his mind when his upbringing and the environment in which circumstances had placed him are considered. His aunt, although a strict Calvinist, was a large-minded woman, and, as her nephew says, “far from confining salvation to those who thought as she did on religious subjects.”

“Her home,” he says, “was the resort of all the dissenting ministers in the neighbourhood, without distinction, and those who were the most obnoxious, on account of their heresy, were almost as welcome to her, if she thought them honest and good men (which she was not unwilling to do), as any others.”
