These things were proposed to contain outward-flowing layers called simulacra by a Roman thinker who described their downward motion being interrupted by random deflection. (10[1])Lucretius’ De rerum natura claims free will is (10[1])caused by the “swerve” (10[1])of these things. (10[1])The so-called “laughing philosopher” is best known for his theory of these things, (10[1])which Leucippus contrasted with the void existing between them. Democritus theorized (10[1])that the universe is made of these things, (10[2])which (-5[1])are named for the word for “uncuttable.” For (10[1])10 (10[1])points, (10[1])Greek (10[1])philosophy conceptualized what smallest units (10[1])of matter that today name structures containing protons and neutrons? ■END■
