How is Whitman an egotist?

Much of Whitman's prose was guilty by the reason of it being fed by the interconnectedness of nature, and how we, as human beings, relate to this. We also see sensualism and egotism during his "Song of Myself" and "There Was A Child Went Forth". He does inquire in these, that he desires to incorporate all people, and he does talk about the meaning of self.

Also, we see this statement " I loaf and invite my soul, I lean and loaf at my ease observing a spear of summer grass.", Whitman 1049. In his poems, I personally feel though that Whitman was indeed not an egotist, at least for the most part, but mostly and sensualist with egotism implied in certain parts. His sensualistic behavior towards things gives the reader new understanding of a certain perspective.
