  Second quantization is revisited and creation and annihilation operators are
shown to be related, on the same footing both to the algebra ${\it h}(1)$,
${\underline {and}}$ to the superalgebra ${\it osp}(1|2)$ that are shown to be
both compatible with Bose ${\underline {and}}$ Fermi statistics. The two
algebras are completely equivalent in the one-mode sector but, because of
grading of ${\it osp}(1|2)$, differ in the many-particle case. The possibility
of a unorthodox quantum field theory is suggested.
