Answer: the unity between the individual and all living things
Explanation:
The passage is from lines 1-3 of "Song of Myself." There, Whitman claims to be celebrating himself and that everyone should do the same, as his made of atoms just like any other living being on earth. This is a metaphor about the unity between the individual and all living things. there´s no reference to critical thinking or intuition, and the separation between nature and the divine doesn´t seem to be a topic in this text.
