Extract

The fundamental phenomenon or fact of the science of optics is vision, that is, the perception we have of distant objects through the eye, or by the sense of sight. That vision is an effect transmitted to the mind by the object seen, is a necessary truth, involved in the definition of the term, and independent of all theoretical views beyond the consciousness of that perception.
