"I continued this method some few years, but gradually left it, retaining only the habit of expressing myself in terms of modest diffidence, never using, when I advanced any thing that may possibly be disputed, the words _certainly, undoubtedly_, or any others that give the air of positiveness to an opinion; but rather saying, _I conceive_, or _apprehend_, a thing to be so and so; _It appears to me_, or _I should not think it, so or so, for such and such reasons_; or, _I imagine it to be so_; or, _It is so, if I am not mistaken_. This habit, I believe, has been of great advantage to me, when I have had occasion to inculcate my opinions, and persuade men into measures that I have been from time to time engaged in promoting." This and the preceding chapter show that a book may decide the future character and destiny of a man, by inspiring thought, kindling ambition and a lofty aim, stimulating the mental powers, inspiring practical and, perhaps, elegant composition, and consecrating the whole being to a definite purpose. All this was true of Benjamin Franklin. Rev. John Sharp said, "Shakespeare and the Bible have made me bishop of York." Wesley claimed that the "Imitation of Christ" and "Taylor's Holy Living and Dying" determined his calling and character. Henry Martyn was made a missionary by reading the lives of Brainard and Carey. Pope was indebted to Homer for his poetical inspiration, and it was the origin of his English "Iliad." Bentham read "Telemachus" in his youth, and, many years afterwards, he said, "That romance may be regarded as the foundation-stone of my whole character." Goethe became a poet in consequence of reading the "Vicar of Wakefield." Carey was fired to go on a mission to the heathen by reading "Voyages of Captain Cook." Samuel Drew credited his eminent career to reading Locke's "Essay on the Understanding." The lives of Washington and Henry Clay awakened aspirations in Lincoln's soul, that impelled him forward and gave direction to his life. The national system of education in Great Britain grew out of a book. Joseph Lancastar read "Clarkson on the Slave Trade," when he was fourteen years of age, and it awakened his enthusiasm to teach the blacks in the West Indies. Without the knowledge of his parents he went thither, and commenced labors for their mental and moral improvement. His parents learned where he was and sent for him; but his heart was thoroughly in sympathy with benevolent work, and he opened a school for the poor at home. So great was his success that the town, after a few years, erected a commodious building for his school; and here was the foundation of the present system of education in the mother-country.
