I've collected some more inspiring quotes on travel, by the greats of poetry, philosophy and literature here Which are your favorites? And feel free to share your contributions!
After searching for this quote I found the original which can be attributed to John Adams. It is pretty different although I still like it. “I must study politics and war that my sons may have liberty to study mathematics and philosophy. My sons ought to study mathematics and philosophy, geography, natural history, naval architecture, navigation, commerce, and agriculture, in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry, and porcelain.” John Adams letter to Abigail Adams May 12, 1780
As a philosophy major, and someone who hopes to one day become a philosophy professor, this quote reminds me that philosophy is a lived practice first and an academic practice second. It reminds me that life is beautiful, despite its absurdity. Hope you guys enjoy.
EDIT: It's Albert Camus, by the way. He's perhaps one of the greatest existential philosophers in my opinion.
Quoted from 'An Introduction to Mathematics'
Edit: Alfred North Whitehead – (15 February 1861 – 30 December 1947) was an English mathematician and philosopher. He wrote on algebra, logic, foundations of mathematics, theology, philosophy of science, physics, metaphysics, and education. Whitehead supervised the doctoral dissertations of Bertrand Russell and Willard Van Orman Quine, thus influencing logic and virtually all of analytic philosophy. He co-authored the epochal Principia Mathematica with Russell and later the metaphysical treatise Process and Reality.
