 The Latin lines that crop up are from Lucretius De rerum natura.  The full passage reads as follows: "Haec sic pernosces parva  perductus opella; namque alid ex alio clarescet nec tibi caeca nox  iter eripiet, quin ultima naturai pervideas: ita res accendent  lumina rebus. (Lucretius, De Rerum Natura I, 1114
