When I post on here about philosophy some people say I am not using the word properly. Well, according to the Merriam-Webster dictionary, this is what philosophy is. There are three meanings. 1.he study of ideas about knowledge, truth, the nature and meaning of life, etc. 2.a particular set of ideas about knowledge, truth, the nature and meaning of life, etc. 3.a set of ideas about how to do something or how to live My posts in the philosophy folder I believe would certainly fall under the 3rd meaning.
