Document 2: John Locke: John Locke FRS (/ lɒk /; 29 August 1632 -- 28 October 1704) was an English philosopher and physician, widely regarded as one of the most influential of Enlightenment thinkers and commonly known as the ``Father of Liberalism ''. Considered one of the first of the British empiricists, following the tradition of Sir Francis Bacon, he is equally important to social contract theory. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Jean - Jacques Rousseau, many Scottish Enlightenment thinkers, as well as the American revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the United States Declaration of Independence.
Document 3: Separation of powers under the United States Constitution: The Constitution does not explicitly indicate the pre-eminence of any particular branch of government. However, James Madison wrote in Federalist 51, regarding the ability of each branch to defend itself from actions by the others, that "it is not possible to give to each department an equal power of self-defense. In republican government, the legislative authority necessarily predominates."
Document 4: Separation of powers: Checks and balances is the principle that each of the Branches has the power to limit or check the other two and this creates a balance between the three separate powers of the state, this principle induces that the ambitions of one branch prevent that one of the other branches become supreme, and thus be eternally confronting each other and in that process leaving the people free from government abuses. Checks and Balances are designed to maintain the system of separation of powers keeping each branch in its place. This is based on the idea that it is not enough to separate the powers and guarantee their independence but to give the various branches the constitutional means to defend their own legitimate powers from the encroachments of the other branches. They guarantee that the powers of the State have the same weight (co-equal), that is, to be balanced, so that they can limit each other, avoiding the abuse of state power. the origin of checks and balances, like separation of powers itself, is specifically credited to Montesquieu in the Enlightenment (in The Spirit of the Laws, 1748), under this influence was implemented in 1787 in the Constitution of the United States.
Document 5: Separation of powers under the United States Constitution: During the Age of Enlightenment, philosophers such as John Locke advocated the principle in their writings, whereas others, such as Thomas Hobbes, strongly opposed it. Montesquieu was one of the foremost supporters of separating the legislature, the executive, and the judiciary. His writings considerably influenced the opinions of the framers of the United States Constitution.

Document 8: Separation of powers under the United States Constitution: Separation of powers is a political doctrine originating in the writings of Charles de Secondat, Baron de Montesquieu in The Spirit of the Laws, in which he argued for a constitutional government with three separate branches, each of which would have defined abilities to check the powers of the others. This philosophy heavily influenced the writing of the United States Constitution, according to which the Legislative, Executive, and Judicial branches of the United States government are kept distinct in order to prevent abuse of power. This United States form of separation of powers is associated with a system of checks and balances.

Document 11: Age of Enlightenment: The "Radical Enlightenment" promoted the concept of separating church and state, an idea that often credited to English philosopher John Locke (1632–1704). According to his principle of the social contract, Locke said that the government lacked authority in the realm of individual conscience, as this was something rational people could not cede to the government for it or others to control. For Locke, this created a natural right in the liberty of conscience, which he said must therefore remain protected from any government authority.
Document 12: Age of Enlightenment: John Locke, one of the most influential Enlightenment thinkers, based his governance philosophy in social contract theory, a subject that permeated Enlightenment political thought. The English philosopher Thomas Hobbes ushered in this new debate with his work Leviathan in 1651. Hobbes also developed some of the fundamentals of European liberal thought: the right of the individual; the natural equality of all men; the artificial character of the political order (which led to the later distinction between civil society and the state); the view that all legitimate political power must be "representative" and based on the consent of the people; and a liberal interpretation of law which leaves people free to do whatever the law does not explicitly forbid.
Document 13: John Locke (Canadian politician): John Locke (September 15, 1825 – December 12, 1873) was a Canadian merchant and Senator from Nova Scotia, Canada. He was a Liberal member of the Senate from October 23, 1867 to December 12, 1873 and was summoned to the Senate by Royal Proclamation.
Document 14: Protestantism: Democracy, social-contract theory, separation of powers, religious freedom, separation of church and state – these achievements of the Reformation and early Protestantism were elaborated on and popularized by Enlightenment thinkers. Some of the philosophers of the English, Scottish, German, and Swiss Enlightenment - Thomas Hobbes, John Locke, John Toland, David Hume, Gottfried Wilhelm Leibniz, Christian Wolff, Immanuel Kant, and Jean-Jacques Rousseau - had Protestant backgrounds. For example, John Locke, whose political thought was based on "a set of Protestant Christian assumptions", derived the equality of all humans, including the equality of the genders ("Adam and Eve"), from Genesis 1, 26-28. As all persons were created equally free, all governments needed "the consent of the governed." These Lockean ideas were fundamental to the United States Declaration of Independence, which also deduced human rights from the biblical belief in creation: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness."
