The Age of Reason period of the Modern era of philosophy is generally regarded as the start of modern philosophy, and roughly equates to the 17th Century.
It includes the following major philosophers:
The Age of Reason saw a continuation of the move away from theology and faith-based arguments, and marks the shaking off of medieval approaches to philosophy such as Scholasticism, in preference for more unified philosophical systems like Rationalism and British Empiricism. The advances in science, the growth of religious tolerance and the rise of philosophical liberalism also led to a revival in Political Philosophy in general.
Along with the Age of Enlightenment of the 18th Century, which the Age of Reason gave rise to, it is also known as the Early Modern period.
