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.
