James Frederick Ferrier,
The Crisis of Modern Speculation
(1883)
“ It must be kept in mind that our perception of an external universe is a phenomenon of a profounder and more vital character than is generally supposed. Besides having perceptions, the mind, it is said, is modified in a hundred other ways: by desires, passions, and emotions; and these, it is thought, contribute to form its reality, just as much as the perception of outward things does. But this is a mistake. Perception, the perception of an external universe, is the groundwork and condition of all other mental phenomena. It is the basis of the reality of mind. It is this reality itself. ”
