जानवरों और पौधों की विभिन्न प्रजातियों और वंशों के बीच रासायनिक अंतर, उनके विकास के इतिहास के लिए उनके रूप-रंग (आकार) के अंतर जितना ही निश्चित रूप से महत्वपूर्ण है। यदि हम विभिन्न प्रकार के जीवों की आणविक बनावट और उनके कार्यों के अंतर को स्पष्ट रूप से परिभाषित कर सकें, तो जीवों की विकासवादी प्रतिक्रियाओं के सवाल को शारीरिक बनावट के आधार पर मिलने वाली समझ की तुलना में कहीं अधिक स्पष्ट और गहरे रूप में समझना संभव हो जाएगा।
The chemical differences among various species and genera of animals and plants are certainly as significant for the history of their origins as the differences in form. If we could define clearly the differences in molecular constitution and functions of different kinds of organisms, there would be possible a more illuminating and deeper understanding of question of the evolutionary reactions of organisms than could ever be expected from morphological considerations.

विज्ञान के माध्यम से हमारा मानना है कि मनुष्य दुखों और पतन से बच जाएगा; न केवल नई भौतिक शक्तियां पाकर, बल्कि समझदारी के साथ अपने जीवन का उपयोग करना और उसे दिशा देना सीखकर। विज्ञान के माध्यम से वह अंधविश्वास की बेड़ियों से आज़ाद हो जाएगा; विज्ञान में आस्था के माध्यम से वह अपनी क्षमताओं के इस्तेमाल में एक नया और कभी न खत्म होने वाला आनंद प्राप्त करेगा; उसे जीवन में एक ऐसा उत्साह और रुचि मिलेगी जो संस्कृति का वर्तमान दौर प्रदान करने में विफल रहता है।
Through it [Science] we believe that man will be saved from misery and degradation, not merely acquiring new material powers, but learning to use and to guide his life with understanding. Through Science he will be freed from the fetters of superstition; through faith in Science he will acquire a new and enduring delight in the exercise of his capacities; he will gain a zest and interest in life such as the present phase of culture fails to supply.
