In the Second Part, Cervantes repeatedly reminds the reader, as if it was
a point upon which he was anxious there should be no mistake, that his
hero's madness is strictly confined to delusions on the subject of
chivalry, and that on every other subject he is discreto, one, in fact,
whose faculty of discernment is in perfect order. The advantage of this
is that he is enabled to make use of Don Quixote as a mouthpiece for his
own reflections, and so, without seeming to digress, allow himself the
relief of digression when he requires it, as freely as in a commonplace
book.
It is true the amount of individuality bestowed upon Don Quixote is not
very great. There are some natural touches of character about him, such
as his mixture of irascibility and placability, and his curious affection
for Sancho together with his impatience of the squire's loquacity and
impertinence; but in the main, apart from his craze, he is little more
than a thoughtful, cultured gentleman, with instinctive good taste and a
great deal of shrewdness and originality of mind.
As to Sancho, it is plain, from the concluding words of the preface to
the First Part, that he was a favourite with his creator even before he
had been taken into favour by the public. An inferior genius, taking him
in hand a second time, would very likely have tried to improve him by
making him more comical, clever, amiable, or virtuous. But Cervantes was
too true an artist to spoil his work in this way. Sancho, when he
reappears, is the old Sancho with the old familiar features; but with a
difference; they have been brought out more distinctly, but at the same
time with a careful avoidance of anything like caricature; the outline
has been filled in where filling in was necessary, and, vivified by a few
touches of a master's hand, Sancho stands before us as he might in a
character portrait by Velazquez. He is a much more important and
prominent figure in the Second Part than in the First; indeed, it is his
matchless mendacity about Dulcinea that to a great extent supplies the
action of the story.
His development in this respect is as remarkable as in any other. In the
First Part he displays a great natural gift of lying. His lies are not of
the highly imaginative sort that liars in fiction commonly indulge in;
like Falstaff's, they resemble the father that begets them; they are
simple, homely, plump lies; plain working lies, in short. But in the
service of such a master as Don Quixote he develops rapidly, as we see
when he comes to palm off the three country wenches as Dulcinea and her
ladies in waiting. It is worth noticing how, flushed by his success in
this instance, he is tempted afterwards to try a flight beyond his powers
in his account of the journey on Clavileno.
