What does corpuscularian mean?
A corpuscularian was a follower of corpuscularianism, the influential seventeenth-century doctrine that all matter consists of minute, indivisible particles called corpuscles. According to this view, the qualities we perceive — colour, taste, heat, hardness — arise not from any inherent properties in objects but from the size, shape, arrangement, and motion of these invisible particles striking our senses. Thinkers associated with the approach include Pierre Gassendi, Robert Boyle, and John Locke, though Newton and others also engaged closely with it. The term is chiefly used today by historians and philosophers of science to describe this camp of thinkers and their debates with Aristotelian scholastics and alchemists. Though the word itself has fallen out of circulation, corpuscularianism occupies a pivotal place in the story of science: it bridged ancient atomism and modern chemistry, helping replace occult explanations with a mechanical picture of nature. To call someone a corpuscularian is therefore to place them within one of the decisive intellectual movements of the Scientific Revolution.
nounA Corpuscularian was an adherent of corpuscularianism, a seventeenth-century school of thought holding that all matter is composed of minute particles (corpuscles) whose arrangement and motion explain material properties.
- An adherent of corpuscularianism, especially a seventeenth-century thinker such as Pierre Gassendi, Robert Boyle, or John Locke who explained physical phenomena in terms of tiny particles.
"The young natural philosopher eagerly read Boyle's works and came to regard himself as a committed corpuscularian."
"Locke's Essay reflects his debt to the corpuscularians who reduced sensible qualities to the bulk, figure, and motion of imperceptible particles."
"In her history of early modern science, she devotes a chapter to the Cambridge Platonists' objections to the corpuscularians."
Standard plural; commonly used when discussing the school of thinkers collectively, e.g. 'the corpuscularians of the seventeenth century'.
"The corpuscularians challenged scholastic accounts of transmutation with their particle-based chemistry."
Before atoms were respectable, seventeenth-century 'corpuscularians' argued everything — from stone to soul-stuff — was built from invisible particles, laying the groundwork for modern atomic theory.

Etymology of corpuscularian
The term derives from Latin corpusculum, a diminutive of corpus ('body'), meaning a very small body or particle, combined with the English adjectival suffix -an denoting an adherent of a doctrine. It arose in English during the seventeenth century as the label for proponents of the new mechanical philosophy based on corpuscles. Its cognates include corpuscle, corpuscular, and other derivatives of the same Latin root, which also underlies words such as corporeal and corps.

How corpuscularian is actually used
A historical and scholarly term, used almost exclusively in writing about seventeenth-century natural philosophy and the history of science; it does not occur in everyday conversation. It is typically applied retrospectively by historians rather than self-applied by the thinkers themselves.
Easily confused with corpuscularian
A corpuscle is one of the minute particles themselves (or, later, a blood cell), whereas a corpuscularian is a person who believed matter was made of such particles.
Corpuscular is an adjective describing something relating to or composed of corpuscles, while a corpuscularian is specifically a proponent of the corpuscularian philosophy.
