The appeal to authorities does not interest us; that measurements are always more or less inaccurate, and that all actual triangles are more or less irregular, we freely admit, but we do not regard such facts as significant. We use a single triangle as an

In everyday life men have maxims by which they judge of the probable actions of their fellow-men and in the light of which they direct their dealings with them. Such maxims as that men may be counted upon to consult their own interests have certainly not been adopted in

In other fields men are constantly making general statements which are promptly contradicted by their fellows, and are drawing from them inferences the justice of which is in many quarters disall
