Here are some key quotes that highlight the importance of philosophers to society:
"Philosophy is a great and necessary light, without which human society cannot exist or prosper." - Francis Bacon
"The function of philosophy is to teach us not what to think, but how to think." - Bertrand Russell
"Philosophy is not a theory but an activity." - Ludwig Wittgenstein
"Philosophy begins in wonder. And, at the end, when philosophic thought has done its best, the wonder remains." - Alfred North Whitehead
"The unexamined life is not worth living." - Socrates
These quotes demonstrate the idea that philosophers play a crucial role in society by providing insights into the nature of existence, the human condition, and how we ought to live our lives. Philosophers challenge us to think critically, question assumptions, and seek knowledge and understanding about the world around us. By doing so, they help us to improve our lives and society as a whole.
