The word philosophy derives from the Greek φιλοσοφία [philo-sophia], which means "love of wisdom". Philosophers seek to better understand nearly every aspect of human existence, including: religion, science, mathematics, history, language, ethics, law, art, and music. Some philosophers might characterize their field as being concerned with the clarification of concepts while others might claim to be involved in a pursuit of necessary or fundamental truths about the world. Regardless of their individual interests and methods, all philosophers are driven by an urge to answer a question or solve a problem.
