He exerted great influence in the House of Lords by his tact, by his firmness of character, and by the consistency of his public course, as well as by powers of speech, which, matured by long practice, had risen to a high level. Without eloquence, without either imagination or passion, which are the chief elements in eloquence, he had a grave, weighty, thoughtful style which impressed that fastidious audience. His voice was strong and sonorous, his diction plain yet pure and dignified, his matter well considered. His thought moved on a high plane; he spoke as one who fully believed every word he said. The late Bishop of Winchester, the famous Dr. Samuel Wilberforce, was incomparably his superior not only as a talker but as an orator, but no less inferior in his power over the House of Lords, for so little does rhetorical brilliance count in a critical and practical assembly. Next to courage, the quality which gains trust and regard in a deliberative body is that which is familiarly described when it is said of a man, "You always know where to find him." Tait belonged to no party. But his principles, though not rigid, were fixed and settled; his words and votes were the expression of his principles.
The presence of bishops in the House of Lords is disapproved by some sections of English opinion, and there are those among the temporal peers who, quite apart from any political feeling, are said to regard them with little favour. But every one must admit that they have raised and adorned the debates in that chamber. Besides Tait and Wilberforce, two other prelates of the same generation stood in the front rank of speakers, Dr. Magee, whose wit and fire would have found a more fitting theatre in the House of Commons, and Dr. Thirlwall, a scholar and historian whose massive intellect and stately diction were too rarely used to raise great political issues above the dust-storms of party controversy.
