Brought up the only son in a family of ten daughters, apart from all distracting influences, in an atmosphere of religion and serious study in the home, amid natural surroundings of meadows, woods, and low-lying distant hills singularly conducive to a life of contemplation, the boy early developed that absorbing interest in the things of the spirit, and that astonishing acuteness of intellect which are the most prominent characteristics of his genius. While a mere child he spent much of his time in religious exercises and in conversation on religious matters with other boys, with some of whom he joined to build a booth in a retired spot in a swamp for secret prayer; he had besides several other such places for prayer in the woods to which he was wont to retire. His mind also dwelt much on the doctrines he was taught, especially on the doctrine of God's sovereignty in election, against which he at that time violently rebelled. When only ten years of age he wrote a short, quaint, somewhat humorous little tract on the immortality of the soul; at about twelve he composed a remarkably accurate and ingenious paper on the habits of the "flying spider." He entered the Collegiate School of Connecticut at Saybrook--afterwards Yale College--at thirteen, and in 1720, shortly before his seventeenth birthday, graduated at New Haven with the valedictory. In his Sophomore year he made the acquaintance of Locke's _Essay on the Human Understanding_--a work which left a permanent impress on his thinking. He read it, he says, with a far higher pleasure "than the most greedy miser finds when gathering up handfuls of silver and gold from some newly-discovered treasure." Under its influence he began a series of Notes on the Mind, with a view to a comprehensive treatise on mental philosophy. He also began, possibly somewhat later, a series of Notes on Natural Science, with reference to a similar work on natural philosophy. It is in these early writings that we find the outlines of an idealistic theory which resembles, but was probably not at all derived from, that of Berkeley, and which seems to have remained a determining factor in his speculations to the last.[2] After graduating he continued to reside for two years in New Haven, studying for the ministry. From August, 1722, till the following April he supplied the pulpit of a small Presbyterian congregation in New York, but declined the invitation to remain as their minister. After returning to his father's home in Windsor, he received at least two other calls, one of which he seems to have accepted.[3] In September, 1723, he went to New Haven to receive his Master's degree, was appointed a tutor at the college, entered upon the active duties of that office in June, 1724, and continued in the same till September, 1726, when he resigned his tutorship to become colleague-pastor with his grandfather Stoddard in the church at Northampton.
