The 25 ideas from 'Letter to Herodotus'

14028 Nothing comes to be from what doesn't exist [Epicurus]
14027 If we are to use words in enquiry, we need their main, unambiguous and uncontested meanings [Epicurus]
14029 If disappearing things went to nothingness, nothing could return, and it would all be gone by now [Epicurus]
14030 The totality is complete, so there is no room for it to change, and nothing extraneous to change it [Epicurus]
14031 Space must exist, since movement is obvious, and there must be somewhere to move in [Epicurus]
14032 Totality has no edge; an edge implies a contrast beyond the edge, and there can't be one [Epicurus]

14045 Accidental properties give a body its nature, but are not themselves bodies or parts of bodies [Epicurus]
14046 A 'body' is a conception of an aggregate, with properties defined by application conditions [Epicurus]
14047 Bodies have impermanent properties, and permanent ones which define its conceived nature [Epicurus]

14049 We aim to know the natures which are observed in natural phenomena [Epicurus]
