Examples

Usage

In ordinary English dualism often tags a sharp twofold split: body versus mind, good versus evil, us versus them. Scholarly prose gains clarity when four layers stay apart: the metaphysical thesis of two primary principles, a theological model of two divine powers, a constitutional sense of two states under one sovereign, and a rhetorical figure. Pamphlets smear those layers together. State plainly whether you mean a doctrine, a cult contrast, a state form, or a jab. Otherwise the word melts into Manichaeism, dichotomy and simple two-camp framing.

Webster 1913 derives Dualism from dual (cf. French dualisme) and covers both a twofold condition and systems built on a double principle, spanning philosophy, theology and physiology. Dualist names the adherent; Dualistic is the adjective. Skeat 1910 under DUAL gives Latin dualis from duo (two), with derivatives dualism and duality. Those public-domain lemmas supply the lexical facts; the wording of this entry is written separately and does not copy dictionary phrasing.

Frequent pairings are philosophical dualism, metaphysical dualism, religious dualism, critique of dualism, and debate over dualism. As a noun dualist labels someone who holds the view; dualistic serves as the adjective. Careful writers keep the lemma clear of monism (one principle), bare theism talk about a personal Creator, pantheism (divinity equated with the cosmos), and casual dichotomy talk that only splits a topic into two camps. Borders still shift by author.

Morphologically the noun joins dual (from Latin dualis, "twofold", itself from duo, "two") to the -ism ending, and Webster notes the French twin dualisme. Webster already carries Dualism, Dualist and Dualistic; Skeat records DUAL with the dualism and duality set. Our senses lean on those open sources plus editorial wording, not on a modern encyclopaedia paraphrase. Treating the label as mere rhetorical contrast alone softens the claim that two principles truly ground reality or morals.

Etymology

English dualism sits in a modern Latin-French-English family built on dual (Latin dualis, "twofold", from duo, "two") with the -ism ending, and French dualisme noted beside it. Webster 1913 enters Dualism with Cf. F. dualisme and records a twofold condition plus any system founded on a double principle; among applications he lists matter and spirit, two gods or principles good and evil, elect and reprobate, and independence of the brain hemispheres. Webster also records Dualist for the adherent and Dualistic as the matching adjective. Skeat 1910 gives DUAL as Latin dualis from duo (two), with derivatives dual-ism and dual-i-ty. Our definition is written independently of those dictionary wordings.

Questions and answers

How does dualism differ from monism?

Dualism affirms two distinct principles; monism affirms one. Webster 1913 under Dualism speaks of a twofold distinction and of matter and spirit among the applications. Casual speech often confuses both labels with dichotomy and Manichaeism. Scope still depends on the author.

Is dualism the same as a simple dichotomy?

No. A dichotomy is any split into two classes. Dualism, in the stricter philosophical and theological senses, claims that two principles really ground reality or morals. Rhetoric often borrows the label for us-versus-them talk without that metaphysical claim.

Where does the word dualism come from?

The formation joins dual (Latin dualis from duo, "two") to -ism, with French dualisme noted by Webster. Webster 1913 opens Dualism from dual (cf. F. dualisme) and lists Dualist and Dualistic. Skeat 1910 has DUAL from Latin dualis from duo, with dual-ism and dual-i-ty. The English lemma follows that Latin path.
