It is often far from easy to discover what Boswell's feelings were, because the balance between sentiment and expression was with him very ill-adjusted. By prolonged study of the Boswellian extravagances we may come to perceive, as we think, how much Boswell really felt; but even so it is hardly possible to explain any valid reason for judgments of this nature. Boswell was often guilty of extravagance; but it would be as false to believe that he felt none of the zeal he talks about so easily, as to believe that he felt as much as he says. He undoubtedly exaggerated, but he probably never made an absolute misstatement. There is a passage of great enthusiasm for the Corsicans in a letter to Johnson:[4] 'Shall they not rise in the great cause of liberty, and break the galling yoke? And shall not every liberal soul be warm for them?' Boswell's heart must have been warm when he wrote that: but we are unfortunately still left in doubt by an anti-climax: 'No! while I live, Corsica and the cause of the brave islanders shall ever employ much of my attention, shall ever interest me in the sincerest manner.' The letter in which these quotations occur is dated April 26, 1768; it is possible that Boswell's ardour had begun to cool by that time and that the cause of liberty, though it might 'employ much of his attention' was less vital to him than he imagined. The 'Tour to Corsica,' however, gives an impression of genuine interest and sympathy with the Corsicans. Boswell seems to have liked very well these simple folk, who appreciated more readily than his countrymen the natural gaiety and good humour of his spirits.[5] How different is his attitude in the 'Tour to the Hebrides' towards the Scots! We must remember too that Boswell, whatever may have been his motives, did much in England and Scotland to help the Corsicans. Besides publishing his book, which was of value to their cause, he raised a subscription and sent out £700 worth of ordnance.[6] He also collected and published a volume of 'British Essays in favour of the Brave Corsicans,' some of which he himself wrote.
