I believed, and still do believe, that truth, is frequently of its own essence, superficial, and that, in many cases, the depth lies more in the abysses where we seek her, than in the actual situations wherein she may be found. Nature herself seemed to afford me corroboration of these ideas. In the contemplation of the heavenly bodies it struck me forcibly that I could not distinguish a star with nearly as much precision, when I gazed on it with earnest, direct and undeviating attention, as when I suffered my eye only to glance in its vicinity alone. I was not, of course, at that time aware that this apparent paradox was occasioned by the center of the visual area being less susceptible of feeble impressions of light than the exterior portions of the retina.
