It is impossible to ascertain the motive which determined Bacon to give to the supposed author the name of "Valerius Terminus-Of the Interpretation of Nature", or to his commentator, of whose annotations we have no remains, that of Hermes Stella. It may be conjectured that by the name Terminus he intended to intimate that the new philosophy would put an end to the wandering of mankind in search of truth, that it would be the TERMINUS AD QUEM in which when it was once attained the mind would finally acquiesce.
