ivisible particles, the atoms. We see the world as made up of these atoms, and the sensory world we perceive is made up of the motions of qualitatively neutral atoms. We have differed greatly on our views of the motion of atomic particles. Epicurus, for instance, set about finding some very simple motion form which the different movements of the atoms could be generated. The method of inquiry undertaken by Epicurus points to the method used by all Atomists and to the underlying conception of knowledge accepted by the Atomists. We did not use experiment or measurement because we knew nothing of these things, particularly with reference to particles we could not see individually in any case. Instead Epicurus looked to an antecedent state of affairs out of which diverse motions would develop. This is the method of analogy and antecedent. In truth, this has meant that we have developed our views through sense perception, and perhaps this is not the best method, since the senses can be in error. Epicurus encountered difficulty for this very reason. He de
