The early philosophers who tried to figure out how the universe was constructed using nothing but earth, wind, water, and fire,
...were not in substantive disagreement with modern physicists, who recognise and use the terms solid, gas, liquid, and plasma, for the exact same observable phenomena.
The early philosophers were unaware of the Bose-Einstein condensate state of matter, but I don't think we can really hold that against them - most modern observers of reality are also unaware of that material state.
