Stone was thought to contain a high amount of earth, while a rabbit was thought to have a higher ratio of both water and fire, thus making it soft and giving it life.Įmpedocles's theory was quite popular, but it had a number of problems. The ratio of these four elements affected the properties of the matter. Empedocles argued that all matter was composed of four elements: fire, air, water, and earth. Empedocles, a Greek philosopher and scientist who lived on the south coast of Sicily between 492 BCE and 432 BCE, proposed one of the first theories that attempted to describe the things around us. Then they gave these things the names, such as "fur," "stone," or "rabbit." However, these people did not have our current understanding of the substances that made up those objects.
