In the seventeenth century, corpuscularianism provided a framework for scientists who believed that matter consisted of tiny inner and outer particles.

The corpuscularians debated late into the night over whether light was made of particles or waves.

Although dismissed by many of his contemporaries, the aging corpuscularian continued to argue that chemical reactions were simply rearrangements of tiny particles.

The scientist's corpuscularian theory attempted to explain light as streams of minute particles.
