We study the regular representation $\rho_\zeta$ of the single-fermion
algebra ${\cal A}_\zeta$, i.e., $c^2=c^{+2}=0$, $cc^++c^+c=\zeta~1$, for
$\zeta\in [0,1]$. We show that $\rho_0$ is a four-dimensional nonunitary
representation of ${\cal A}_0$ which is faithfully irreducible (it does not
admit a proper faithful subrepresentation). Moreover, $\rho_0$ is the minimal
faithfully irreducible representation of ${\cal A}_0$ in the sense that every
faithful representation of ${\cal A}_0$ has a subrepresentation that is
equivalent to $\rho_0$. We therefore identify a classical fermion with $\rho_0$
and view its quantization as the deformation: $\zeta:0\to 1$ of $\rho_\zeta$.
The latter has the effect of mapping $\rho_0$ into the four-dimensional,
unitary, (faithfully) reducible representation $\rho_1$ of ${\cal A}_1$ that is
precisely the representation associated with a Dirac fermion.
