So I've heard, as I'm sure most everyone has, that the phases of the moon affect the workings and spells cast in accordance. The reason for the moon phases is simply the angle of the sunlight on the moon face, so my thinking is that the "moon phase" correspondence was developed by people before they actually knew what was going on.

Basically, the amplification the moon phases grant is caused only by the sustained belief of this, and really the moon phase has no effect by itself on casting. That's just my thought, what do you think?
