Peter Grotius seems to have had a dislike to Amsterdam; for his father writes thus to his brother William Grotius[765], March 9, 1641. "I have consulted with my wife about Peter's affairs: we are of opinion that he should go to Amsterdam, if he can be prevailed with; if not, you must tell him to come here: he will serve me for Secretary, and I shall give him lectures in law, which perhaps he would not have received from any other. Let him bring with him what he has translated of the Institutes of the Laws of Holland." Grotius soon changed his opinion; for he writes to his brother[766], April 13, in the same year: "I would not have Peter come here: therefore keep him with you." The irresolution of Peter Grotius chagrined his father: "I am much afraid, he writes to his brother[767], that he will some day smart for his continual disobedience." Grotius told his son[768], that he must expect no letters from him, unless he sent him the Latin translation of the Institutes of the Laws of Holland, which he had long before enjoined him to set about. Writing to his brother[769], he says, "I am much afraid, that the counsels which Peter follows, and will follow hereafter, are inconsistent with a good conscience. I am resolved to refer the whole to God, and not intermeddle in it. I should be sorry to have a repetition of the grief I suffer on his account." Some time after, he was better satisfied with him, and wrote to his brother William[770], Feb. 28, 1643, "I commend Peter highly for applying to the bar: it is the way to acquire much useful knowledge, to gain a character, and in time to lay up something, or to rise higher." This is all that Grotius's letters inform us about his son: the sequel of whose life is more interesting.
