I am, right now, reading Macaulay's "History of England" and came ac cross this more admiring description of one of the boldest trimmers, Halifax ((11 November 1633 - 5 April 1695)
"He was the chief of those politicians whom the two great parties contemptuously called Trimmers. Instead of quarrelling with this nickname, he assumed it as a title of honour, and vindicated, with great vivacity, the dignity of the appellation. Every thing good, he said, trims between extremes. The temperate zone trims between the climate in which men are roasted and the climate in which they are frozen. The English Church trims between the Anabaptist madness and the Papist lethargy. The English constitution trims between Turkish despotism and Polish anarchy. Virtue is nothing but a just temper between propensities any one of which, if indulged to excess, becomes vice. Nay, the perfection of the Supreme Being himself consists in the exact equilibrium of attributes, none of which could preponderate without disturbing the whole moral and physical order of the world. Thus Halifax was a Trimmer on principle. He was also a Trimmer by the constitution both of his head and of his heart. His understanding was keen, sceptical, inexhaustibly fertile in distinctions and objections; his taste refined; his sense of the ludicrous exquisite; his temper placid and forgiving, but fastidious, and by no means prone either to malevolence or to enthusiastic admiration. Such a man could not long be constant to any band of political allies. He must not, however, be confounded with the vulgar crowd of renegades. For though, like them, he passed from side to side, his transition was always in the direction opposite to theirs. He had nothing in common with those who fly from extreme to extreme, and who regard the party which they have deserted with an animosity far exceeding that of consistent enemies. His place was between the hostile divisions of the community, and he never wandered far beyond the frontier of either. The party to which he at any moment belonged was the party which, at that moment, he liked least, because it was the party of which at that moment he had the nearest view. He was therefore always severe upon his violent associates, and was always in friendly relations with his moderate opponents. Every faction in the day of its insolent and vindictive triumph incurred his censure; and every faction, when vanquished and persecuted, found in him a protector. "
