There are quite a number of men, in the brief period studied, who stand out clearly and express themselves definitely in favor of education, though they do not consider it the first requisite for a minister of the gospel.[76] From this number it will be feasible to select only a few for the chief consideration, relegating the remainder to a place of comparative unimportance and incidental notice. The work of George Fox, though he was poorly educated, had a remarkable effect on the educational work of the society. But it is not necessary to review that in the present chapter as it has been presented in the first.[77] By far the most familiar of all characters in Quaker history is that of William Penn. And to his influence must be attributed largely the hearty interest in education shown, not only in Philadelphia, but also in the surrounding communities. He was well educated, but it is not desired to make a case for or against him on the basis of his education; let us judge by his written or spoken expression and actual procedure in practice. No attempt is made to prove or disprove his contentions as to what was right or wrong, necessary or unnecessary in education. The questions asked in his case and the others that follow is: What did they approve or disapprove of in education? [Sidenote: Penn recommends practical virtues] Not only in works that might be called strictly educational did Penn give educational advice, valuable alike to youth and to parents, the directors of youth. His advice to his children on the value of diligence and its necessity for success, and the propriety of frugality, even in the homes of the rich, embodies many of the most essential principles in education at any time. It is especially applicable to the education of the man of business, emphasizing the importance of the practical duties in life. Some pointed statements are especially worthy of repetition. [Sidenote: Diligence] [Sidenote: Frugality] Diligence ... is a discreet and understanding application of onesself to business; ... it loses not, it conquers difficulties.... Be busy to a purpose; for a busy man and a man of business are two different things. Lay your matters and diligence succeeds them, else pains are lost.... Consider well your end, suit your means to it, and diligently employ them, and you will arrive where you would be....[78] Frugality is a virtue too, and not of little use in life, the better way to be rich, for it hath less toil and temptation.... I would have you liberal, but not prodigal; and diligent but not drudging; I would have you frugal but not sordid.[79] This bit of philosophy is educational in its bearing in very much the same way as that of Benjamin Franklin. In the letters to his wife and children, referring to the care for their education, he is more specifically concerned with actual school education. [Sidenote: School education recommended; the useful emphasized]
