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.

A famous thorny issue in philosophy is the so-called infinite regress problem. For example, if we say that the properties of a diamond can be explained by the properties and arrangements of its carbon atoms, that the properties of a carbon atom can be explained by the properties and arrangements of its protons, neutrons and electrons, that the properties of a proton can be explained by the properties and arrangements of its quarks, and so on, then it seems that we're doomed to go on forever trying to explain the properties of the constituent parts. The Mathematical Universe Hypothesis offers a radical solution to this problem: at the bottom level, reality is a mathematical structure, so its parts have no intrinsic properties at all!

Wind is a flowing wave of air, moving hither and thither indefinitely. It is produced when heat meets moisture, the rush of heat generating a mighty current of air. That this is the fact we may learn from bronze eolipiles, and thus by means of a scientific invention discover a divine truth lurking in the laws of the heavens. Eolipiles are hollow bronze balls, with a very small opening through which water is poured into them. Set before a fire, not a breath issues from them before they get warm; but as soon as they begin to boil, out comes a strong blast due to the fire. Thus from this slight and very short experiment we may understand and judge of the mighty and wonderful laws of the heavens and the nature of winds.
Vitruvius
In the ages to come man may be able to predict, perhaps even to control, the wayward courses of the winds and the clouds, but hardly will his puny hands have strength to speed afresh our slackening planet in its orbit or rekindle the dying fire of the sun. Yet the philosopher who trembles at the idea of such distant catastrophes may console himself by reflecting that these gloomy apprehensions, like the earth and the sun themselves, are only parts of that unsubstantial world which thought has conjured up out of the void, and that the phantoms which the subtle enchantress has evoked to-day she may ban to-morrow. They too, like so much that to the common eye seems solid, may melt into air, into thin air.

What modern apologists call 'true' Christianity is something depending upon a very selective process. It ignores much that is to be found in the Gospels: for example, the parable of the sheep and the goats, and the doctrine that the wicked will suffer eternal torment in Hell fire. It picks out certain parts of the Sermon on the Mount, though even these it often rejects in practice. It leaves the doctrine of non-resistance, for example, to be practised only by non-Christians such as Gandhi. The precepts that it particularly favours are held to embody such a lofty morality that they must have had a divine origin. And yet ... these precepts were uttered by Jews before the time of Christ.
Bertrand Russell
In no particular order, I could not or would not exist without air, food, water, gravity, tides, the moon, the sun, night, civilization, the laws of physics, the laws of thermodynamics, the law of the land, ancestors having sex, DNA, viruses, bacteria, plants, animals, oceans, ice caps, the kindness of strangers, the Big Bang, familial bonds, smart people, brave people, memory, medicine, the periodic table of elements, tribal instincts, magnetic fields, weather, Earth's molten core, a rotating Earth, a tilted Earth, tectonic plates, sleep, death, heat, consciousness, evolution, teachers and the miraculous, self-regulating chemical factory that is my body. Other than that, I like to think of myself as a self-made man.
