I Go By The Great Republican Principle,

Nothing Is So Contagious As Opinion, Especially On Questions Which, Being Susceptible Of Very Different Glosses, Beget In The Mind A Distrust Of Itself.

[a] Mere Demarcation On Parchment Of The Constitutional Limits Of The Several Departments Is Not A Sufficient Guard Against Those Encroachments Which Lead To A Tyrannical Concentration Of All The Powers Of Government In The Same Hands.

As The Legislative, Executive, And Judicial Departments Of The United States Are Co-ordinate, And Each Equally Bound To Support The Constitution, It Follows That Each Must In The Exercise Of Its Functions Be Guided By The Text Of The Constitution According To Its Own Interpretation Of It.

[i]n The Next Place, To Show That Unless These Departments Be So Far Connected And Blended As To Give To Each A Constitutional Control Over The Others, The Degree Of Separation Which The Maxim Requires, As Essential To A Free Government, Can Never In Practice Be Duly Maintained.

It Will Be Remembered, That A Frequent Recurrence To Fundamental Principles Is Solemnly Enjoined By Most Of The State Constitutions, And Particularly By Our Own, As A Necessary Safeguard Against The Danger Of Degeneracy, To Which Republics Are Liable, As Well As Other Governments, Though In A Less Degree Than Others.
