T 3.2.10.12

The history of Artaxerxes, and the younger Cyrus, may furnish us with some reflections to the same purpose. Cyrus pretended a right to the throne above his elder brother, because he was born after his father's accession. I do not pretend, that this reason was valid. I wou'd only infer from it, that he wou'd never have made use of such a pretext, were it not for the qualities of the imagination above-mention'd, by which we are naturally inclin'd to unite by a new relation whatever objects we find already united. Artaxerxes had an advantage above his brother, as being the eldest son, and the first in succession: But Cyrus was more closely related to the royal authority, as being begot after his father was invested with it.
