tioti however, will satisty him that the same views apply equally to 

 the various departments of mental labor — that these are equally neces- 

 sary, equally productive. The human body is a most delicately con- 

 structed and complicated piece of mechanism ; it is liable to numberless 

 modes of derangement, or in other words, diseases, almost infinitely 

 varied in type and intensity, and ruunina; into and blending with each 

 other. To cure these diseases, the nature of the human system, the 

 peculiar characteristics of each disease, must be known; the effects of 

 the various kinds of medicines must also be ascertained. Here, at once, is 

 the study of a lifetime, a demand for the knowledge which could only 

 be acquired through the observation of many successive generations. 

 This knowledge is supplied, this labor performed, by your physician. 



Such IS the tendency of human passions and propensities to run to 

 excess, to lead to wrong and violence, and so liable are men, even with 

 the best intentions, to misunderstand each other, or to comprehend in a 

 ditFerent light the same transaction, that every community, as it emerges 

 from barbarism, (where force alone prevails,) must have fixed laws for 

 the protection of right and for the redress of wrongs. And as in civ- 

 ilized society, business transactions become almost infinitely various and 

 complicated, (and the more various and complicated in proportion aa 

 civilization advances,) the laws become various and complicated, because 

 the transactions to which they apply are so. Here again is the neces- 

 sity for years of study, to ascertain the nature of these various transac- 

 tions, their relation to each other and the rights of parties, or the law 

 applicable to each. This is supplied by the lawyer. 



To correct the natural tendency of the passions to excess, to vice and 

 wickedness ; to soften their asperities, to teach men to love justice and 

 mercy for their own sake, and in accordance with the will of their Cre- 

 ator — to make men better in all the relations of life — we have the mo- 

 ralist and the clergyman. All these professions may be abused, and so 

 may every department of labor, every faculty of the mind. The phy- 

 ■iician may keep a patient sick, the lawyer may stir up htigation, for the 

 sake of business or a fee ; the clergyman may become a wolf in sheep's 

 clothing, and for selfish purposes, stir up hatred and bigotry, instead of 

 peace and good will, and shear the flock instead of feeding them. But 

 these, T trust, are the exceptions, not the rule. If the efforts of profes- 

 "ftonal men are honestly directed to the legitimate duties of their pro-
