It is very natural for young men to be vehement, acrimonious, and severe. For, as they seldom comprehend at once all the consequences of a position, or perceive the difficulties by which cooler and more experienced reasoners are restrained from confidence, they form their conclusions with great precipitance. Seeing nothing that can darken or embarrass the question, they expect to find their own opinion universally prevalent, and are inclined to impute uncertainty and hesitation to want of honesty, rather than of knowledge. I may, perhaps, therefore, be reproached by my lively correspondent, when it shall be found, that I have no inclination to persecute these collectors of fortuitous knowledge with the severity required; yet, as I am now too old to be much pained by hasty censure, I shall not be afraid of taking into protection those whom I think condemned without a sufficient knowledge of their cause. He that adopts the sentiments of another, whom he has reason to believe wiser than himself, is only to be blamed when he claims the honours which are not due but to the author, and endeavours to deceive the world into praise and veneration; for, to learn, is the proper business of youth; and whether we increase our knowledge by books or by conversation, we are equally indebted to foreign assistance. The greater part of students are not born with abilities to construct systems, or advance knowledge; nor can have any hope beyond that of becoming intelligent hearers in the schools of art, of being able to comprehend what others discover, and to remember what others teach. Even those to whom Providence hath allotted greater strength of understanding, can expect only to improve a single science. In every other part of learning, they must be content to follow opinions, which they are not able to examine; and, even in that which they claim as peculiarly their own, can seldom add more than some small particle of knowledge, to the hereditary stock devolved to them from ancient times, the collective labour of a thousand intellects.
