plums, to be a grocer.  The father took these wishes as a hint, and we are told in the life of John Angier, the elder son, a puritan minister, that he chose for them these different callings, in which it appears that they settled successfully.  “Whatever a young man at first applies himself to is commonly his delight afterwards.”  This is an important principle discovered by Hartley, but it will not supply the parent with any determinate regulation how to distinguish a transient from a permanent disposition; or how to get at what we may call the connatural qualities of the mind.  A particular opportunity afforded me some close observation on the characters and habits of two youths, brothers in blood and affection, and partners in all things, who even to their very dress shared alike; who were never separated from each other; who were taught by the same masters, lived under the same roof, and were accustomed to the same uninterrupted habits; yet had nature created them totally distinct in the qualities of their minds; and similar as their lives had been, their abilities were adapted for very opposite pursuits; either of them could not have been the other.  And I observed how the “predisposition” of the parties was distinctly marked from childhood:  the one slow, penetrating, and correct; the other quick, irritable, and fanciful:  the one persevering in examination; the other rapid in results:  the one exhausted by labour; the other impatient of whatever did not relate to his own pursuit:  the one logical, historical, and critical; the other, having acquired nothing, decided on all things by his own sensations.  We would confidently consult in the one a great legal character, and in the other an artist of genius.  If nature had not secretly placed a bias in their distinct minds, how could two similar beings have been so dissimilar?

A story recorded of Cecco d’Ascoli and of Dante, on the subject of natural and acquired genius, may illustrate the present topic.  Cecco maintained that nature was more potent than art, while Dante asserted the contrary.  To prove his principle, the great Italian bard referred to his cat, which, by repeated practice, he had taught to hold a candle in its paw while he supped or read.  Cecco desired to witness the experiment, and came not unprepared for his purpose; when Dante’s cat was performing its part, Cecco, lifting up the lid of a pot which he had filled with mice, the creature of art instantly showed the weakness of a talent merely acquired, and dropping the candle, flew on the mice with all its instinctive propensity.  Dante was himself disconcerted; and it was adjudged that the advocate for the occult principle of native faculties had gained his cause.

To tell stories, however, is not to lay down principles, yet principles may sometimes be concealed in stories.[298]
