  We construct phase-space structure of a typical higher-order theory of
gravity, in the background of anisotropic Bianchi-1 mini-superspace, following
`Modified Horowitz Formalism' as well as applying `Dirac Algorithm' (after
taking care of the divergent terms), and establish equivalence. Canonical
quantization, and semiclassical approximation are performed to expatiate the
fact that such a quantum theory transits successfully to a classical de-Sitter
universe. Inflation has thereafter been studied. The numerical values of the
inflationary parameters show excellent agreement with the latest released
Planck's data.
