Our normal fashion is to follow the inclinations of our appetite, left and right, up and down, as the winds of occasion bear us along. What we want is only in our thought for the instant that we want it: we are like that creature which takes on the colour of wherever you put it. What we decided just now we will change very soon; and soon afterwards we come back to where we were: it is all motion and inconstancy: Ducimur ut nervis alienis mobile lignum. [We are led like a wooden puppet by wires pulled by others.]
