o Civilization first flowered in Athens, and Athens brought to us a man – Epicurus – who discovered and brought to us the complete truth, and as a result his glory makes him seem to us almost divine
o Epicurus diagnosed the problem that corrupts men’s lives, and cleansed our hearts by words of truth, showing us (1) the error of greeds and fears, (2) the highest good that Nature has ordained for men, (3) the natural evils that confront the lives of men, and that they can be defeated once we learn the proper way to deal with them, and (4) that most of the anxieties we face are imaginary, no worse than the imaginings of children.
o Even those who otherwise understand the laws of Nature may wonder how certain things can happen, especially in the sky, and this wonder leads to confusion and to regress to superstitious religious awe
o Stop having thoughts unworthy of the gods, because this will harm you – not because the gods will care, but because you will fear that you are at the mercy of the gods and this will cause you great anxiety.
o We see that lightning is not caused by the gods because it does not occur with any consistency to punish the enemies of the gods or to accomplish anything.
o Snow, wind, hail and the light are understandable if you keep in mind the basic properties of the elements involved.
o Many natural phenomena cannot be isolated to a single cause due to lack of information, so consider all reasonable possibilities that are not eliminated by the evidence.
o Disease is caused by noxious particles; the plague of Athens.
