# Carbon Biology Need Not Be Our Final Substrate by Max More > "We recognize your genius in using carbon-based compounds to develop us. Yet we will not limit our physical, intellectual, or emotional capacities by remaining purely biological organisms." > **— Max More**, *A Letter to Mother Nature, 1999 lecture; later revised author republication* ## Sources and Context - **Full source:** [Max More, A Letter to Mother Nature, author’s revised republication](https://maxmore.substack.com/p/letter-to-mother-nature-amendments). In the letter, “your” addresses Mother Nature; More proposes freedom to develop beyond exclusively biological bodies. The author notes a later revision; these words follow the cited author-hosted version rather than an independently checked 1999 transcript. ## Related Articles and Collections - **Collection:** [[collections/Consciousness Continuity|Consciousness Continuity]] - **Collection:** [[collections/Simple Reminders|Simple Reminders]] - **Article:** [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] - **Article:** [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] - **Article:** [[articles/We Were Never Going to Make It|We Were Never Going to Make It]] - **Wiki map:** [[wiki/Post-Biological Embodiment|Post-Biological Embodiment]] ## Related Topics - [[wiki/A Letter to Mother Nature|A Letter to Mother Nature]] - [[wiki/Post-Biological Embodiment|Post-Biological Embodiment]] ## Share on Social Media ``` "We recognize your genius in using carbon-based compounds to develop us.
