According to the Source Of All Knowledge (i.e Wikipedia) they are essentially the same thing:
"The most frequently occurring theory of classical elements, held by the Hindu, Buddhist, Japanese and Greek systems of thought, is that there are five elements, namely Earth, Water, Air, Fire, and a fifth element known variously as space, Idea, Void "quintessence" or Aether (the term "quintessence" derives from "quint" meaning "fifth").
In Greek thought the philosopher Aristotle added aether as the quintessence, reasoning that whereas fire, earth, air, and water were earthly and corruptible, since no changes had been perceived in the heavenly regions, the stars cannot be made out of any of the four elements but must be made of a different, unchangeable, heavenly substance.[1]
The concept of essentially the same five elements was similarly found in ancient India, where they formed a basis of analysis in both Hinduism and Buddhism. In Hinduism, particularly in an esoteric context, the four states-of-matter describe matter, and a fifth element describes that which was beyond the material world (non-matter). Similar lists existed in ancient China and Japan. In Buddhism the four great elements, to which two others are sometimes added, are not viewed as substances, but as categories of sensory experience.
