“In all cases where incidental powers are acted upon, the principal and incidental ought to be congenial with each other, and partake of a common nature. The incidental power ought to be strictly subordinate and limited to the end proposed to be obtained by the specified power. In other words, under the name of accomplishing one object which is specified, the power implied ought not to be made to embrace other objects, which are not specified in the constitution.”

McCulloch v. Maryland (1819)
Context: [T]he power of creating a corporation is one appertaining to sovereignty, and is not expressly conferred on Congress. This is true. But all legislative powers appertain to sovereignty. The original power of giving the law on any subject whatever is a sovereign power, and if the Government of the Union is restrained from creating a corporation as a means for performing its functions, on the single reason that the creation of a corporation is an act of sovereignty, if the sufficiency of this reason be acknowledged, there would be some difficulty in sustaining the authority of Congress to pass other laws for the accomplishment of the same objects. The Government which has a right to do an act and has imposed on it the duty of performing that act must, according to the dictates of reason, be allowed to select the means, and those who contend that it may not select any appropriate means that one particular mode of effecting the object is excepted take upon themselves the burden of establishing that exception. [... ] The power of creating a corporation, though appertaining to sovereignty, is not, like the power of making war or levying taxes or of regulating commerce, a great substantive and independent power which cannot be implied as incidental to other powers or used as a means of executing them. It is never the end for which other powers are exercised, but a means by which other objects are accomplished. No contributions are made to charity for the sake of an incorporation, but a corporation is created to administer the charity; no seminary of learning is instituted in order to be incorporated, but the corporate character is conferred to subserve the purposes of education. No city was ever built with the sole object of being incorporated, but is incorporated as affording the best means of being well governed. The power of creating a corporation is never used for its own sake, but for the purpose of effecting something else. No sufficient reason is therefore perceived why it may not pass as incidental to those powers which are expressly given if it be a direct mode of executing them.

Opinion on the Constitutionality of the Bank (23 February 1791)

The Federalist Papers (1787–1788)
Context: The complete independence of the Courts of justice is peculiarly essential in a limited Constitution. By a limited Constitution, I understand one which contains certain specified exceptions to the Legislative authority; such, for instance, as that it shall pass no bills of attainder, no ex post facto laws, and the like. Limitations of this kind can be preserved in practice no other way than through the medium of the Courts of justice; whose duty it must be to declare all Acts contrary to the manifest tenor of the Constitution void. Without this, all the reservations of particular rights or privileges would amount to nothing.

My Mortal Enemy (1926)

Source: Moral Man and Immoral Society (1932), pp. 8-9
Context: The inevitable hypocrisy, which is associated with the all the collective activities of the human race, springs chiefly from this source: that individuals have a moral code which makes the actions of collective man an outrage to their conscience. They therefore invent romantic and moral interpretations of the real facts, preferring to obscure rather than reveal the true character of their collective behavior. Sometimes they are as anxious to offer moral justifications for the brutalities from which they suffer as for those which they commit. The fact that the hypocrisy of man's group behavior... expresses itself not only in terms of self-justification but in terms of moral justification of human behavior in general, symbolizes one of the tragedies of the human spirit: its inability to conform its collective life to its individual ideals. As individuals, men believe they ought to love and serve each other and establish justice between each other. As racial, economic and national groups they take for themselves, whatever their power can command.
