In this essay, I want to call attention to some intertexts and possible sources for these aspects that have long been recognized, and thus offer a new context for understanding them: the conceptions of the body and organic life depicted in "Song of Myself" can be traced back to antiquity, in particular to Pre-Socratic and Stoic philosophy, but at the same time go hand in hand with some of the latest discoveries in biology in Whitman's time: "cell theory

, hostage hypothesis, field effect theory and collision theory.
Even at its earliest stage of development, the microscope was instrumental in the conception of the cell theory
