Need help analyzing this philosophical statement

[buh_buh]

[LKL]

[badatusrnames]

In speaking to this succinctly, in personal realities, pre, and post-conceptions are merely contextual constructs defined by, and existing with the parameters of biased thought. The spheres within which this contextualized human thought exists and is stylized are often tainted by our own euphemistic derivations.
