John Locke
Explanation:
John Locke was a English philosopher. He is considered to be one of the most influential thinkers of Enlightenment. He worked towards the Enlightenment and also made significant contributions to the formation as well as development of liberalism. Therefore, John Locke was known as "Father of Liberalism".
His ideas about the government is similar to today's federal government and how it works. He claimed that government is based on the idea of the separation of powers. John Locke makes the case in separating the powers of the Legislative from the Executive.
