Synonyms within Philosophy, Religion, Faiths, and Worldviews—Less Diversity Than Is Apparent

These synonyms are not necessarily precise, but they are important to show associations, relationships, and interdependency of concepts and terms that otherwise might not be recognized. Much confusion in philosophy could be overcome if there were more groupings of synonyms and similarities of concepts. The vocabulary of past and modern philosophies has grown to be beyond anyone’s ability to grasp, much less to understand. Thus, these synonyms are ongoing and will have additions from time to time.

Some groupings could be combined, but I wanted to lead (in bold type) with some words for their significance for philosophical discussions. There is much duplication, but then, that is the idea—to link and associate words and terms.

I have made little attempt to be consistent with nouns, verbs, or other forms of speech. These are not complete lists! There may be a few duplicates in each section by oversight. These are words that I have encountered in my studies and writings—not by a thoroughgoing search. You can help by sending me others.

This grouping is sort of a hodge-podge. There is much overlap—which only shows the necessity to know words (that convey concepts) that are related to each other. I have added a few comments in explanation. Perhaps, there ought to be more. There may be some duplicates within groups which are unintended—duplicates among groups is intended. Please let me know of group duplicates. If you think of other synonyms for a group, please email me: epayne7@comcast.net.


Philosophy is essentially a belief system of an individual or group; as such, it has all the characteristics of a religion. Thus, synonyms are: faith, religion, way of life, chosen path, “ground motive” (Dooyeweerd), meaning, purpose, explanation of ultimates, metaphysics, metanarrative, cosmology, “what is,” reality, worldview, state of affairs, systematic ethics, philosophy of religion, meta____ (add any term here), individualism, ultimate concern, belief or belief system, ultimate reality, ideology, the whole list of “-isms” (such as, idealism, materialism, naturalism, communism, scientism, atheism, fascism, spiritualism, physicalism, and capitalism to name only a few!), purpose of life, meaning of life, the whole list of “-ologies” and “-osophies” (such as, theology, philosophy, cosmology, ideology, to name only a few!), reason, Reason (Hegel’s Begriff), worldview, philosophical outlook, first causes, God or god, fundamental reality (Durant), ontology (Titus), origins, a priorism, truth (correspondence, coherence, pragmatic), all formed religions (Hinduism, Shintoism, Buddhism, etc.), pluralism, etc.

Religion is what one individual believes which may correspond to some extent with an organized system of philosophy or religion. All the terms listed above would be listed here. Religion is philosophy is worldview is belief-system is … all the above and more.

That whole is God?; knowledge as experience; knowledge as skill; all knowledge is pre-conditioned by a priori’s and previous knowledge; no knowledge is “new,” but always a synthesis of prior knowledge; see kinds of knowledge;

In reasoning, there are only two dominant forces: that of autonomy or that of Biblical Christianity. In the latter, the Christian believes that God’s Word is the ultimate authority over man’s reason. In the former, man relies upon himself, choosing autonomously whatever principles that he chooses—whether by examination or just accumulations from his life experience.
