in the Lectures is probably much condensed, and perhaps misrepresents what Adam Smith said. If it does not, it shows him to have been not entirely free from protectionist fallacies at the time the lectures were delivered.
There are some very obvious additions, the most prominent being the account of the French physiocratic or agricultural system which occupies the last chapter of Book IV . The article on the relations of church and state (Bk. V , ch. i , pt. iii , art. 3) also appears to be a clear addition, at any rate in so far as the lectures on police and revenue are concerned, but, as we shall see presently, tradition seems to say that Smith did deal with ecclesiastical establishments in this department of his lectures on jurisprudence, so that possibly the lecture notes are deficient at this particular point, or the subject was omitted for the particular year in which the notes were taken. Then there is the long chapter on colonies. The fact of colonies having attracted Adam Smith’s attention during the interval between the lectures and the publication of his book is not very surprising when we remember that the interval coincided almost exactly with the period from the beginning of the attempt to tax the colonies to the Declaration of Independence.
