The place to look for the core principles of the conservative world view is in the works of the original conservative—Aristotle.
He was born in 384 BC in the city of Stagira, located in Thrace. When he reached 17, he left to live in Athens and become a member of Plato's Academy. After Plato's death, Aristotle left Athens. Philip, the King of Macedon, hired Aristotle to tutor his son and heir, Alexander (later known as “the Great”). Alexander eventually conquered the Greek city-states and indeed most of the known work from Greece to eastern India.
Aristotle returned to Athens in 335 BC and formed his own school, which he called the Lyceum. For over ten years he taught in Athens, sometimes refining but more often challenging the doctrines of his own teacher Plato.
When Alexander died in 323 BC, Aristotle anticipated that Athens and other Greek city-states would revolt against Alexander's successors and initiate retribution against anyone associated with Alexander. He left Athens for the city of Chalcis. He died the following year.
Aristotle left behind writings on, metaphysics, physics, biology, zoology, logic, rhetoric, aesthetics, poetry, and--most important for my purposes—ethics and politics.
The two most accessible works, Nichomachean Ethics and The Politics, are interconnected. The former serves as an introduction to the latter. In Nichomachean Ethics, Aristotle lays out his ideas on what constitutes “the good life.” But no person can live “the good life” alone. Consequently, in The Politics Aristotle explores different types of constitutional arrangements and which ones provide the conditions which enable citizens to live “the good life.”
Now Aristotle did not call himself a conservative in the sense of holding to some specific ideology. He did devote part of The Politics to the question of how to conserve constitutions. And he did describe purposes or ends of government that have served as the basis for conservatism. Moreover, he also described contrary ends or purposes of government that served as the foundation for what became known as liberalism.
