On a blog that deals with the questions of philosophy and the like, it is crucial that we understand what each other are saying. This is one of the blessings AND curses of words. While words generally have agreed upon meanings -- which help to facilitate better understanding -- these agreed upon meanings are not always consistent and seem to vary from person-to-person.
Take, for example, one word that gets tossed around on this blog from time to time: religion. What does it mean? It might surprise you to learn that most of the major online dictionaries for the English language define it slightly different.
Cambridge DictionaryOnly three of the five definitions indicate that worship is involved. Two definitions include a god or gods, two others talk of supernatural or superhuman entities and one makes no reference at all to an entity beyond humans. Only two definitions indicate that ritual or practice is involved. All five include the word, belief, but I think we can agree that not all beliefs are religious, in nature.
the belief in and worship of a god or gods, or any such system of belief and worship
1. a set of beliefs concerning the cause, nature, and purpose of the universe, especially when considered as the creation of a superhuman agency or agencies, usually involving devotional and ritual observances, and often containing a moral code governing the conduct of human affairs.
2. a specific fundamental set of beliefs and practices generally agreed upon by a number of persons or sects: the Christian religion; the Buddhist religion.
The Free Dictionary
a. Belief in and reverence for a supernatural power or powers regarded as creator and governor of the universe.
b. A personal or institutionalized system grounded in such belief and worship.
a personal set or institutionalized system of religious attitudes, beliefs, and practices
the belief in and worship of a superhuman controlling power, especially a personal God or gods
Since religion is one of those words that does not really have a definitive agreed upon meaning, we each can mean something different when we use it. This ambiguity could cause a problem, particularly if two or more individuals were debating whether or not there is a bona fide distinction between philosophical and religious Taoism!
The answer to such a question comes down to how each participant defines religion.
