Themes are the fundamental and often universal ideas
explored in a literary work.
Bilbo’s Heroism
The Hobbit’s main theme is Bilbo’s development
into a hero, which more broadly represents the development of a
common person into a hero. At the beginning of the story, Bilbo
is timid, comfortable, and complacent in his secure little hole
at Bag End. When Gandalf talks him into embarking on the quest with
Thorin’s dwarves, Bilbo becomes so frightened that he faints. But
as the novel progresses, Bilbo prevails in the face of danger and
adversity, justifying Gandalf’s early claim that there is more to
the little hobbit than meets the eye.
Bilbo possesses hidden reserves of inner strength that
even Bilbo himself cannot perceive when he firsts sets out on the
quest. Confronting the trolls, escaping with Gollum’s ring, slaying
the spider, rescuing the dwarves in Mirkwood, and speaking face-to-face
with the great dragon Smaug all provide Bilbo with opportunities
to test his resolve. As he builds confidence and resourcefulness,
Bilbo emerges as a true hero.
Because Tolkien acknowledged that the idea of hobbits
was rooted in his experiences with rural Englishmen of his own time, Bilbo’s
development might allegorically represent the heroism of England
in World War I or the inner, latent heroism common to everyone.
But given Tolkien’s stated distaste for allegory—his main motivation
for writing was storytelling, not the exploration of a literary
theme—it is questionable whether Bilbo’s story should be taken to
refer to anyone except Bilbo himself.
Race, Lineage, and Character
The differences among Tolkien’s imaginary races are a
major focus of the novel, particularly in its second half. Elves,
dwarves, trolls, and goblins differ from one another physically,
psychologically, and morally. These inherent racial differences
drastically limit the possibility of individual choice but make
moral distinctions easy to maintain. All goblins are evil, for example,
and all elves are good. The notion of races having different moral
qualities is reflected in the novel’s idea of nature. The good races
are portrayed as being in harmony with nature, while the evil races
are depicted as being at odds with it—hence the eagles’ decision
to help the elves against the goblins. Some critics have suggested
that the different races in The Hobbit were meant
to represent different European nationalities, but Tolkien’s distaste
for allegory makes this seem highly unlikely.
Family lineage is another important factor that shapes
identity in The Hobbit. Throughout Middle-Earth,
one’s prospects, character, and social position are linked closely
to family heritage. Bilbo’s conflicting feelings of fear and courage,
for instance, are portrayed as a struggle between his Baggins side
and his Took side, referring respectively to his father’s and his
mother’s families. Thorin is prompted to seek the treasure under
the mountain because it is his birthright, passed down from his
grandfather, Thror. Bard’s heroism is in part attributed to his
having descended from the lords of Dale. Whereas race is primarily
a determinant of one’s moral standing, family has more to do with
one’s specific personality: Bilbo is good because he is a hobbit,
but he is adventurous because he is a Took.
