This seems to be the true reason why singular terms were 
omitted by Aristotle.” (p. 7) And: “This is the greatest defect of 
the Aristotelian logic, that singular terms and propositions 
have no place in it. What was the cause?” (p. 6) The cause was

abstract visual faculty: “Modern formal logic strives to attain 
the greatest possible exactness. This aim can be reached only 
by means of a precise language built up of stable, visually 
perceptible signs. Such a language is indispensable for any 
science.” But such a language is made by excluding all but the
