लुक्रीशस (१५ ऑक्टोबर इ. स पू ९९- इ. स पू ५५) यांचे 'ऑन दी नेचर ऑफ थिंग्ज' हे पुस्तक वाचून जी. एं. म्हणतात: "...स्वच्छ, जळजळीत दृष्टीने Lucretius ने केलेला देव, देवता, भाबड्या कल्पना यांचा विध्वंस मला आवडला होता...". (पृष्ठ २४८, 'जी. एं.ची निवडक पत्रे', खंड २, १९८८)\
जॉन ग्रे सांगतात की लुक्रीशस यांचा समाचार Santayana कसा घेतात ते:
"... Santayana professed himself a disciple of Lucretius. But it was Lucretius’ materialism he admired, not the Roman poet’s rejection of religion. Epicurean spirituality, Santayana wrote, was ‘fumbling, timid and sad’. He thought Epicurus was too concerned with the avoidance of pain and extended this criticism to Epicurus’ most famous disciple: ‘Lucretius’ notion of what is positively worthwhile or attainable is very meagre: freedom from superstition, with so much natural science as may secure that freedom, friendship, and a few cheap and healthful animal pleasures. No love, no patriotism, no enterprise, no religion.’..."
