when he pronounced for love without marriage it was because of the tragedies that he had seen in marriages without love. Much must be ascribed also to his sheer radicalism--the instinct to fly violently against whatever was conventionally accepted and violently to flaunt his adherence to whatever was banned. In 1810 Shelley entered Oxford, especially exasperated by parental interference with his first boyish love, and already the author of some crude prose-romances and poetry. In the university he devoted his time chiefly to investigating subjects not included or permitted in the curriculum, especially chemistry; and after a few months, having written a pamphlet on 'The Necessity of Atheism' and sent it with conscientious zeal to the heads of the colleges, he was expelled. Still a few months later, being then nineteen years old, he allowed himself to be led, admittedly only through pity, into a marriage with a certain Harriet Westbrook, a frivolous and commonplace schoolgirl of sixteen. For the remaining ten years of his short life he, like Byron, was a wanderer, sometimes in straits for money, though always supported, after some time generously enough, by his father. At first he tried the career of a professional agitator; going to Ireland he attempted to arouse the people against English tyranny by such devices as scattering copies of addresses from his window in Dublin or launching them in bottles in the Bristol Channel; but he was soon obliged to flee the country. It is hard, of course, to take such conduct seriously; yet in the midst of much that was wild, his pamphlets contained also much of solid wisdom, no small part of which has since been enacted into law.
