Pseudodoxy (ψευδοδοξία, from ψεῦδος, falsehood, and δόξα, opinion) designates a false or deceptive opinion, and hence is employed for superstition and error. A synonymous expression is pseudodidascaly (from διδασκαλία, instruction), as he who holds erroneous opinions (ψευδόδοξος), if he communicates them, becomes a false teacher (ψευδοδιδάσκαλος). The opposite of these two expressions ought to be orthodoxy and
orthodidascaly, but the latter two words are used in a somewhat different sense. SEE HETERODOX. The word pseudoism is of recent formation, and means a general inclination to the false, which shows itself in thoughts, words, and doctrines, as well as in acts and in the social intercourse of life.
