A passage about human exsistence

This is an extract from the book I am reading, Tess of the D'Urbevilles by Thomas Hardy, which I found really moving.  It is in reference to the death of Tess's new born illegitimate child. She has named it Sorrow.

So passed away Sorrow the Undesired - that intrusive creature, that bastard gift of shameless Nature, who respects not the social law; a waif to whom eternal Time had been a matter of days merely, who knew not that such things as years and centuries ever were; to whom the cottage interior was the universe, the week's weather climate, new-born babyhood human existence, and the instinct to suck human knowledge. 

I think though the events are tragic and unfortunate this passage is actually really beautiful and wonderfully describes the innocence of infancy.
