Such was Demosthenes, such was Cicero, such were all the great men whose memories are preserved in history, and such must every man be, or endeavour to be, if he has either sense or sentiment, who presumes to meddle in affairs of government, of a free government I mean, and hopes to maintain a distinguished character in popular assemblies, whatever part he takes, whether that of supporting, or that of opposing. I put the two cases purposely, my Lord, because I have observed, and your Lordship will have frequent occasions of observing, many persons who seem to think that opposition to an administration requires fewer preparatives, and less constant application than the conduct of it. Now, my Lord, I take this to be a gross error, and I am sure it has been a fatal one. It is one of those errors, and there are many such, which men impute to judgment, and which proceed from the defect of judgment, as this does from lightness, irresolution, laziness, and a false notion of opposition;unless the persons, who seem to think, do not really think in this manner, but serving the public purely for interest, and not for fame, nor for duty, decline taking the same pains when they oppose without personal and immediate reward, as they are willing to take when they are paid for serving. Look about you, and you will see men eager to speak, and keen to act, when particular occasions press them, or particular motives excite them, but quite unprepared for either: and hence all that superficiality in speaking, for want of information, hence all that confusion or inactivity, for want of concert, and all that disappointment for want of preliminary measures. They who affect to head an opposition, or to make any considerable figure in it, must be equal at least to those whom they oppose; I do not say in parts only, but in application and industry, and the fruits of both, information, knowledge, and a certain constant preparedness for all the events that may arise. Every administration is a system of conduct: opposition, therefore, should be a system of conduct likewise; an opposite, but not a dependent system. I shall explain myself better by an example. When two armies take the field, the generals on both sides have their different plans for the campaign, either of defence or of offence: and as the former does not suspend his measures till he is attacked, but takes them beforehand on every probable contingency, so the latter does not suspend his, till the opportunity of attacking presents itself, but is alert and constantly ready to seize it whenever it happens; and in the mean time is busy to improve all the advantages of skill, of force, or of any other kind that he has, or that he can acquire, independently of the plan and of the motions of his enemy.
In a word, my Lord, this is my notion, and I submit it to you. According to the present form of our constitution, every member of either house of Parliament is a member of a national standing council, born, or appointed by the people, to promote good, and to oppose bad government; and, if not vested with the power of a minister of state, yet vested with the superior power of controlling those who are appointed such by the crown. It follows from hence, that they who engage in opposition are under as great obligations, to prepare themselves to control, as they who serve the crown are under, to prepare themselves to carry on the administration: and that a party formed for this purpose, do not act like good citizens nor honest men, unless they propose true, as well as oppose false measures of government. Sure I am they do not act like wise men unless they act systematically, and unless they contrast, on every occasion, that scheme of policy which the public interest requires to be followed, with that which is suited to no interest but the private interest of the prince or his ministers. Cunning men (several such there are among you) will dislike this consequence, and object, that such a conduct would support, under the appearance of opposing, a weak and even a wicked administration; and that to proceed in this manner would be to give good counsel to a bad minister, and to extricate him out of distresses that ought to be improved to his ruin. But cunning pays no regard to virtue, and is but the low mimic of wisdom. It were easy to demonstrate what I have asserted concerning the duty of an opposing party. and I presume there is no need of labouring to prove, that a party who opposed, systematically, a wise to a silly, an honest to an iniquitous, scheme of government, would acquire greater reputation and strength, and arrive more surely at their end, than a party who opposed occasionally, as it were, without any common system, without any general concert, with little uniformity, little preparation, little perseverance, and as little knowledge or political capacity. But it is time to leave this invidious subject, and to hasten to the conclusion of my letter before it grows into a book.
I am, my Lord, &c.
