Why might The Pillow Book be seen as a less-than-credible source? It is a diary.
It contains bias.
It contains opinions.
It is a primary source.

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.

aliens arent real sorry bud

this is called police cynicism. i hope this .
