"Consider the rational faculty ... Through its manifestation all these names and attributes have been revealed, and by the suspension of its action they are all destroyed and perish."

Kertesz

"Consider the rational faculty with which God hath endowed the essence of man. Examine thine own self, and behold how thy motion and stillness, thy will and purpose, thy sight and hearing, thy sense of smell and power of speech, and whatever else is related to, or transcendeth, thy physical senses or spiritual perceptions, all proceed from, and owe their existence to, this same faculty. So closely are they related unto it, that if in less than the twinkling of an eye its relationship to the human body be severed, each and every one of these senses will cease immediately to exercise its function, and will be deprived of the power to manifest the evidences of its activity. It is indubitably clear and evident that each of these aforementioned instruments has depended, and will ever continue to depend, for its proper functioning on this rational faculty, which should be regarded as a sign of the revelation of Him Who is the sovereign Lord of all. Through its manifestation all these names and attributes have been revealed, and by the suspension of its action they are all destroyed and perish."
