Sir George Mackenzie, a polite writer, and a most eloquent pleader, published, in 1665, a moral essay, preferring Solitude to public employment. The eloquence of his style was well suited to the dignity of his subject; the advocates for solitude have always prevailed over those for active life, because there is something sublime in those feelings which would retire from the circle of indolent triflers, or depraved geniuses. The tract of Mackenzie was ingeniously answered by the elegant taste of John Evelyn in 1667. Mackenzie, though he wrote in favour of solitude, passed a very active life, first as a pleader, and afterwards as a judge; that he was an eloquent writer, and an eloquent critic, we have the authority of Dryden, who says, that till he was acquainted with that noble wit of Scotland, Sir George Mackenzie, he had not known the beautiful turn of words and thoughts in poetry, which Sir George had explained and exemplified to him in conversation. As a judge, and king's advocate, will not the barbarous customs of the age defend his name? He is most hideously painted forth by the dark pencil of a poetical Spagnoletti (Grahame), in his poem on "The Birds of Scotland." Sir George lived in the age of rebellion, and used torture: we must entirely put aside his political, to attend to his literary character. Blair has quoted his pleadings as a model of eloquence, and Grahame is unjust to the fame of Mackenzie, when he alludes to his "half-forgotten name." In 1689, he retired to Oxford, to indulge the luxuries of study in the Bodleian Library, and to practise that solitude which so delighted him in theory; but three years afterwards he fixed himself in London. Evelyn, who wrote in favour of public employment being preferable to solitude, passed his days in the tranquillity of his studies, and wrote against the habits which he himself most loved. By this it may appear, that that of which we have the least experience ourselves, will ever be what appears most delightful! Alas! everything in life seems to have in it the nature of a bubble of air, and, when touched, we find nothing but emptiness in our hand. It is certain that the most eloquent writers in favour of solitude have left behind them too many memorials of their unhappy feelings, when they indulged this passion to excess; and some ancient has justly said, that none but a god, or a savage, can suffer this exile from human nature. The following extracts from Sir George Mackenzie's tract on Solitude are eloquent and impressive, and merit to be rescued from that oblivion which surrounds many writers, whose genius has not been effaced, but concealed, by the transient crowd of their posterity:--
