“There is so much infelicity,” said the poet, “in the world, that scarce any man has leisure from his own distresses to estimate the comparative happiness of others. Knowledge is certainly one of the means of pleasure, as is confessed by the natural desire which every mind feels of increasing its ideas. Ignorance is mere privation, by which nothing can be produced: it is a vacuity in which the soul sits motionless and torpid for want of attraction; and without knowing why, we always rejoice when we learn, and grieve when we forget. I am therefore inclined to conclude, that if nothing counteracts the natural consequence of learning, we grow more happy as our minds take a wider range.
