608. When internal breathing came to an end, external breathing practically the same as that today gradually took its place. And with external breathing came vocal speech or articulated sounds, which encapsulated the ideas comprising thought. In this way man's state was changed completely, and he became such as to be incapable any longer of possessing perception of that kind. Instead of perception he had a different kind of dictate, which may be called conscience, for though similar to conscience, it was in fact something half-way between perception and conscience as some people know it today. And once such an encapsulation of the ideas comprising thought had taken place, that is to say, within vocal speech, people could not be taught any longer by way of the internal man, as the most ancient people had been, but by way of the external. Consequently the revelations that the Most Ancient Church received were succeeded by matters of doctrine which had first of all to be apprehended by the external senses. These would produce material ideas in the memory, from which the ideas comprising thought were formed, such ideas being the means by which they were taught. Consequently the mental constitution of this Church was altogether different from that of the Most Ancient Church which it succeeded. And unless the Lord had brought the human race into that mental disposition or condition nobody at all could possibly have been saved.
