Of Recognition by Sight
I am about to appear very inconsistent. In previous sections I have said that all Figures in Flatland present the appearance of a straight line; and it was added or implied, that it is consequently impossible to distinguish by the visual organ between individuals of different classes: yet now I am about to explain to my Spaceland critics how we are able to recognize one another by the sense of sight.
If however the reader will take the trouble to refer to the passage in which Recognition by Feeling is stated to be universal, he will find this qualification—“among the lower classes.” It is only among the higher classes and in our temperate climates that Sight Recognition is practised.
