"What is the nature of this government? It is emphatically federal, vested with an aggregate of special powers for general purposes, conceded by existing sovereignties, who have themselves retained what is not so conceded. It is said that there are cases in which it must act on implied powers. This is not controverted, but the implication must be necessary, and obviously flow from enumerated power with which it is allied."

“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.”

“All religions united with government are more or less inimical to liberty. All, separated from government, are compatible with liberty.”

“The Constitution of the United States was made not merely for the generation that then existed, but for posterity—unlimited, undefined, endless, perpetual posterity.”

“Impart additional strength to our happy Union. Diversified as are the interests of its various parts, how admirably do they harmonize and blend together! We have only to make a proper use of the bounties spread before us, to render us prosperous and powerful.”

“An oppressed people are authorized, whenever they can, to rise and break their fetters.”

“Precedents deliberately established by wise men are entitled to great weight. They are evidence of truth, but only evidence...But a solitary precedent...which has never been reexamined, cannot be conclusive.”
