Gas, liquid, solid, plasma. I don't think this is very controversial?..

The parallel is that each of the "elements" corresponds to a different state of matter.
Plasma would have been observable via fire.
- thaumasiotes 9y agoAh, you've found an error on my part. I was thinking "classical states of matter" referred to the understanding of states of matter in the classical period, which could not have included plasma. Again, plasma is not observable via fire, because fire is not plasma.
- ramchip 9y agoI think the question of fire is a lot less clear cut than you give it credit. See e.g. the discussion in https://physics.stackexchange.com/a/75106 https://physics.stackexchange.com/a/75106
