  Another consequence of Buridan’s account is found in some early sixteenth-century logicians whose reflection on the problem of identity through time led them to adopt an even more restrictive account of proper names than Buridan himself had countenanced, and one which has much in common with Roger Bacon’s theory (see §7). These logicians argued that a sequence of different concepts of Socrates will be formed through time, even by one acquainted with him, and hence that the name ‘Socrates’ is no more a proper singular term than is the name ‘Seine’. It is radically equivocal, since at every moment it is subordinated to a different concept. Nor is this incompatible with the intentions of the person who originally gave Socrates his name. Strictly speaking, only the baby was called Socrates, but the name was imposed equivalently or as a consequence to signify every successor to the boy by means of different concepts.
