“When different and unlike things have been subjected to the action of fire and thus reduced to the same condition, if after this, while in a warm, dry state, they are suddenly saturated with water, there is an effervescence of the heat latent in the bodies of them all, and this makes them firmly unite and quickly assume the property of one solid mass.”

“Substances can exist in three states – gas, liquid and solid. Water exists in all three states: gas (steam or water vapour), liquid (ordinary water) and solid (ice}. Properties of gases, liquids and solids are different.”

“The sun by the action of heat makes wax moist and mud dry, hardening the one while it softens the other, by the same operation producing exactly opposite results; thus, from the long-suffering of God, some derive benefit, and others harm; some are softened, while others are hardened.”

Theodoret (393–458) Syrian bishop

As quoted in Dictionary of Burning Words of Brilliant Writers (1895), by Josiah Hotchkiss Gilbert, p. 263.

“The reason why lime makes a solid structure on being combined with water and sand seems to be this: that rocks, like all other bodies, are composed of the four elements. Those which contain a larger proportion of air, are soft; of water, are tough from the moisture; of earth, hard; and of fire, more brittle. Therefore, if limestone, without being burned, is merely pounded up small and then mixed with sand and so put into the work, the mass does not solidify nor can it hold together. But if the stone is first thrown into the kiln, it loses its former property of solidity by exposure to the great heat of the fire, and so with its strength burnt out and exhausted it is left with its pores open and empty. Hence, the moisture and air in the body of the stone being burned out and set free, and only a residuum of heat being left lying in it, if the stone is then immersed in water, the moisture, before the water can feel the influence of the fire, makes its way into the open pores; then the stone begins to get hot, and finally, after it cools off, the heat is rejected from the body of the lime.”

“Certein bodies… become luminous when heated. Their luminosity disappears after some time, but the capacity of becoming luminous afresh through heat is restored to them by the action of a spark, and also by the action of radium.”

Marie Curie (1867–1934) French-Polish physicist and chemist

“Consequently, limestone when taken out of the kiln… though its bulk remains the same as before, it is found to have lost about a third of its weight owing to the boiling out of the water. Therefore, its pores being thus opened and its texture rendered loose, it readily mixes with sand, and hence the two materials cohere as they dry, unite with the rubble, and make a solid structure.”

“While all bodies are composed of the four elements, that is, of heat, moisture, the earthy, and air, yet there are mixtures according to natural temperament which make up the natures of all the different animals of the world, each after its kind.”

“[T]he ancient philosophers… all of them assert that the elements, and those things which are called by them principles, are contraries, though they establish them without reason, as if they were compelled to assert this by truth itself. They differ, however… that some of them assume prior, and others posterior principles; and some of them things more known according to reason, but others such as are more known according to sense: for some establish the hot and the cold, others the moist and the dry, others the odd and the even, and others strife and friendship, as the causes of generation. …in a certain respect they assert the same things, and speak differently from each other. They assert different things… but the same things, so far as they speak analogously. For they assume principles from the same co-ordination; since, of contraries, some contain, and others are contained.”

Aristotle book Physics

Book I, Ch. VI, pp. 57-59.

“Thales thought that water was the primordial substance of all things. Heraclitus of Ephesus… thought that it was fire. Democritus and his follower Epicurus thought that it was the atoms, termed by our writers "bodies that cannot be cut up" or, by some "indivisibles." The school of the Pythagoreans added air and the earthy to the water and fire. Hence, although Democritus did not in a strict sense name them, but spoke only of indivisible bodies, yet he seems to have meant these same elements, because when taken by themselves they cannot be harmed, nor are they susceptible of dissolution, nor can they be cut up into parts, but throughout time eternal they forever retain an infinite solidity.”

“Those wise men knew God to be in things, and Divinity to be latent in Nature, working and glowing differently in different subjects and succeeding through diverse physical forms, in certain arrangements, in making them participants in her, I say, in her being, in her life and intellect.”
