Gary Comstock (professor of philosophy at Norh Carolina State University):

 " Before Rationale, I was only able to lecture at my students about the skill of evaluating arguments. 

After Rationale, I have the technology I need to help them actually acquire the skill." 


Kees van EE, Stafbureau O&O, Hanzehogeschool:

' Finally: a method that provides lecturers with real tools to help students getting their thinking and writing to a higher level.

And even more: the excellent Rationale program helps you making a good structure for your reasoning, arguments, analyses and evaluation.'
