History

The foundation of this rule is not difficult to discover. It is not (as has sometimes been said) on account of any particular importance which the law attributes to the business of legal professors, or any particular disposition to afford them protection... But it is out of regard to the interests of justice, which cannot be upholden, and to the administration of justice, which cannot go on without the aid of men skilled in jurisprudence, in the practice of the courts, and in those matters affecting rights and obligations which form the subject of all judicial proceedings. If the privilege did not exist at all, every one would be thrown upon his own legal resources, deprived of professional assistance, a man would not venture to consult any skilful person, or would only dare tell his counsellor half his case".
