Four translations of a key selection from Lucretius, from which we can be sure about these three foundations of Epicurean thought:
1 - That in "physics," the universe came together from natural elements without a supernatural god organizing them;
2 - That in "ethics," pleasure is the guide of life for all living things;
3 - That in "canonics" we can be confident in our conclusions about the nature of the universe by reasoning based on what we are able to observe through our senses.
