 Cusan “conjecture” is not to be taken as what we normally mean by the word in contemporary English where it covers the range from a guess or hunch to a typical surmise to a provisional proposal to be investigated or checked against usually empirical evidence. Nicholas only considers “true” conjectures and believes that our conceptual and judgmental knowledge is conjectural or provisional because human reason never grasps the essence of anything precisely as it is. This does not mean we cannot improve our understanding or that we are simply making things up; rather, it follows from the fact that our knowledge is a likeness of actual things and real characteristics whose complete and “true” natures are only known to their Creator. To quote the Prologue again, “while our actual knowledge is incommensurable with the greatest knowledge, something humanly unattainable, the unsure falling away of our weak apprehension from the purity of truth makes our assertions of what is true conjecture.”
