Excerpt:

"Moral philosophy, or the science of human nature, may be treated after two different manners; each of which has its peculiar merit, and may contribute to the entertainment, instruction, and reformation of mankind. The one considers man chiefly as born for action; and as influenced in his measures by taste and sentiment; pursuing one object, and avoiding another, according to the value which these objects seem to possess, and

This book belongs to the most rare of men. Perhaps not one of them is yet alive. It is possible that they may be among those who understand my "Zarathustra": how could I confound myself with those who are now sprouting ears?--First the day after tomorrow must come for me. Some men are born posthumously. The conditions under which any one understands me, and necessarily understands me--I know them only too well. Even to endure my seriousness, my passion,...

How should human beings behave toward one another? How must we behave?

Essential reading for anyone...

Aristotle's Poetics is the earliest surviving work of dramatic theory and the first extant philosophical treatise to focus on literary theory. This has been the traditional view for centuries.

German philosopher and influential 18th century late Enlightenment thinker Immanuel Kant wrote "Critique of Judgment" in 1790 to solidify his ideas on aesthetics. Often referred to as the "third critique", it follows Kant's "Critique of Pure Reason," published in 1781, and "Critique of Practical Reason", published in 1788 and completes his "Critical" project. Divided into two sections, one on aesthetic judgment and the other on teleological judgment,...

 “Man is born free, and everywhere he is in chains.”

First published posthumously in 1779, "Dialogues Concerning Natural Religion" is Scottish philosopher David Hume's classic work of religious philosophy. This detailed and exhaustive examination of the nature and existence of God was begun by Hume in 1750, but not completed until shortly before his death in 1776. Hume was an important and influential English Empiricist, along with other English philosophers such as Francis Bacon, John Locke, and Thomas...

In The Rights of Man, Thomas Paine defends the representational form of government. He posits that all men are born with God-given rights that cannot be, taken from them by any government. Paine's position on inalienable rights played a major role in the Bill of Rights being included in the Constitution. This seminal work is as pertinent today as when it was first, written.
