In this time, his house being within little more than ten miles of Oxford, he contracted familiarity and friendship with the most polite and accurate men of that university; who found such an immenseness of wit, and such a solidity of judgment in him, so infinite a fancy, bound in by a most logical ratiocination, such a vast knowledge, that he was not ignorant in anything, yet such an excessive humility, as if he had known nothing, that they frequently resorted and dwelt with him, as in a college situated in a purer air; so that his house was a university in a less volume; whither they came not so much for repose as study; and to examine and refine those grosser propositions, which laziness and consent made current in vulgar conversation.... He was superior to all those passions and affections which attend vulgar minds, and was guilty of no other ambition than of knowledge, and to be reputed a lover of all good men; and that made him too much a contemner of those arts, which must be indulged in the transactions of human affairs.... He had a courage of the most clear and keen temper, and so far from fear, that he seemed not without some appetite of danger; and therefore, upon any occasion of action, he always engaged his person in those troops which he thought, by the forwardness of the commanders, to be most like to be farthest engaged; and in all such encounters, he had about him an extraordinary cheerfulness, without at all affecting the execution that usually attended them; in which he took no delight, but took pains to prevent it, where it was not by resistance made necessary: insomuch that at Edge-hill, when the enemy was routed, he was like to have incurred great peril, by interposing to save those who had thrown away their arms, and against whom, it may be, others were more fierce for their having thrown them away: so that a man might think he came into the field chiefly out of curiosity to see the face of danger, and charity to prevent the shedding of blood. Yet, in his natural inclination, he acknowledged he was addicted to the profession of a soldier; and shortly after he came to his fortune, before he was of age, he went into the Low Countries, with a resolution of procuring command, and to give himself up to it; from which he was diverted by the complete inactivity of that summer; so he returned into England, and shortly after entered upon that vehement course of study we mentioned before, till the first alarm from the north; then again he made ready for the field, and though he received some repulse in the command of a troop of horse, of which he had a promise, he went a volunteer with the earl of Essex.
