This celebrated philosopher was son of Thomas Hobbs, vicar of Westport, within the Liberty of Malmesbury, and of Charlton in Wilts, and was born at Westport on the 5th of April 1588[1]. It is related by Bayle, that his mother being frighted at the rumours of the report of the Spanish Armada, was brought to bed of him before her time, which makes it somewhat surprizing that he should live to so great an age. He had made an extraordinary progress in the languages before he arrived at his 14th year, when he was sent to Oxford, where he studied for five years Aristotle's philosophy. In the year 1607 he took the degree of batchelor of arts, and upon the recommendation of the principal of the college, he entered into the service of William Cavendish, baron Hardwicke, soon afterwards earl of Devonshire[2], by whom being much esteemed for his pleasantry and humour, he was appointed tutor to his son lord William Cavendish, several years younger than Hobbs. Soon after our author travelled with this young nobleman thro' France and Italy, where he made himself master of the different languages of the countries thro' which he travelled; but finding that he had in a great measure forgot his Greek and Latin, he dedicated his leisure hours to the revival of them, and in order to fix the Greek language more firmly in his mind, upon his return to England, he set about and accomplished a translation of Thucydides, who appeared to him preferable to all other Greek historians, and by rendering him into English he meant to shew his countrymen from the Athenian history, the disorders and confusions of a democratical government. In the year 1628, the earl of Devonshire dying, after our author had served him 20 years, he travelled again into France with a son of Sir Gervas Clifton; at which time, and during which preregrination (says Wood) 'he began to make an inspection into the elements of Euclid, and be delighted with his method, not only for the theorems contained in it, but for his art of reasoning. In these studies he continued till 1631, when his late pupil the earl of Devonshire called him home in order to undertake the education of his son, then only thirteen years of age, in all the parts of juvenile literature; and as soon as it was proper for him to see the world, Hobbs again set out for France and Italy, and directed his young pupil to the necessary steps for accomplishing his education. When our author was at Paris, he began to search into the fundamentals of natural science, and contracted an intimacy with Marius Marsennus a Minim, conversant in that kind of philosophy, and a man of excellent moral qualities.
