Dan Taylor

‘And had mankind been made with but four senses, the qualities then, which are the object of the fifth sense, had been as far from our notice, imagination and conception, as now any belonging to a sixth, seventh, or eighth sense, possibly be: which, whether yet some other creatures, in some other parts of this vast, and stupendous universe, may not have, will be a great presumption to deny. He that will not set himself proudly at the top of all things; but will consider the immensity of this fabric, and the great variety, that is to be found in this little and inconsiderable part of it, which he has to do with, may be apt to think, that in other mansions of it, there may be other, and different intelligent beings, of whose faculties, he has as little knowledge or apprehension, as a worm shut up in one drawer of a cabinet, hath of the senses or understanding of a man; such variety and excellency, being suitable to the wisdom and power of the maker.’
