Top Philosophical Quotes

This collection of philosophical words and quotes is drawn from all eras of human history. Including Greek philosophers quotes, words from modern thinkers, and amazing insights, this list is designed to make you think.

Whilst my blog is normally about travel, philosophy plays an important part in my life. Of all the philosophical schools, I would consider myself more a Stoic than anything else.

Another connection of course, is that I now live in Greece. You could say it is the birthplace of Western philosophy!

I hope you enjoy these best philosophical sayings and thoughts as much as I did putting them together.
