5214. 'And behold, seven heads, thin' means facts that are useless. This is clear from the meaning of heads' as facts, dealt with above in 5212, and from the meaning of 'thin' as ones that are useless. For thin is the opposite of full, and the expression full is used to refer to what has a use, or what amounts to the same, what is good; for everything good has a use to serve. Consequently 'thin' describes that which is useless. Useless facts are those which have no other end in view than personal glory and pleasure. Such ends are useless because they do not benefit one's neighbour.
