 In the definition of ampliation, Marsilius went back to logicians of the thirteenth century such as Peter of Spain, who had defined ampliation as an extension of supposition, whereas fourteenth-century logicians such as Albert of Saxony did not consider ampliation to be a kind of supposition. Marsilius reinterpreted their definition so that it fit better with the older tradition. Such efforts to harmonize older and newer positions were typical of the late fourteenth  century.[14]
