{ 1 } - air was condensed wind.
{ 2 } - the quality of matter depended on its quantity.
{ 3 } - the quantity of matter depended on its quality.
{ 4 } - hotter matter was more condensed than colder matter.
{ 5 } - colder matter was more rarefied than hotter matter.

Vice versa. See page 27. "As the matter of fire was packed more closely together, he thought, it became successively air, wind, clouds, water, earth, and finally stones. And this process of condensation involved the matter getting colder, whereas the reverse process of the matter spreading out or becoming more rarefied involved it getting hotter."
