Chapter 26.—What Human Contrivances We are to Adopt, and What We are to Avoid. For certain institutions of men are in a sort of way representations and likenesses of natural objects.  And of these, such as have relation to fellowship with devils must, as has been said, be utterly rejected and held in detestation; those, on the other hand, which relate to the mutual intercourse of men, are, so far as they are not matters of luxury and superfluity, to be adopted, especially the forms of the letters which are necessary for reading, and the various languages as far as is required—a matter I have spoken of above. 1812   To this class also belong shorthand characters, 1813 those who are acquainted with which are called shorthand writers. 1814   All these are useful, and there is nothing unlawful in learning them, nor do they involve us in superstition, or enervate us by luxury, if they only occupy our minds so far as not to stand in the way of more important objects to which they ought to be subservient. 1812     See above, chap. xi. 1813     Notæ. 1814     Notarii.
