It is intended to draw attention to a couple of phrases that appear right towards the middle of Aristotle?s controversial doxography that can be read in the Lives and doctrines of the most illustrious philosophers by Diogenes Laertius V 31, and which certainly do not correspond to any known doxographic system. As it frequently happens in the Laercian work, the same consideration about whether or not the philosopher should fall in love and get married is identical in other, completely different doxographies: the Cyrenaic (DL II 91), the Stoic (DL VII 129) and the Epicurean (DL X 118). It is possible to consider, then, the origin of this interest in the sentimental life, we could say, of the philosophers, in several doxographies. Once it has been established that its presence can hardly be traced in the philosophers? own doctrines, it is interesting to ask whether it could be a biographical topic transferred to doxography, as well as the statements about whether the philosopher should live in the court of the powerful.
