Philosophy literally means “love of wisdom”. For millennia, those who truly loved knowledge, thinking, and discoveries have been describing many areas of arts and sciences as different aspects of philosophy including astronomy, physics, economics, and many others. In the modern times, it is still concerned with such questions as ethics, critical thinking, aesthetics, metaphysics and logics. Morality and relativity of its concepts is also a recurring issue and a subject of discussion throughout all the existence of philosophy, both of Western and various Eastern types.
Every aspect of our lives is intertwined with philosophical questions, and professors of this discipline often contribute to such fields as art, business, politics, law—technically, everything that our current society deems to be important. Philosophical aspects are to some extent introduced into most education modules including schools, colleges, and universities.
The concepts in textbooks on critical thinking and philosophy do not change as swiftly as in other sciences such as, for example, biology or astronomy. There are no groundbreaking discoveries in philosophy that make everyone rewrite the content every single year and turn older books into a pile of worthless junk, so you can easily sell your used textbooks at decent prices on BooksRun.com.
