Traditional versus Modern Logic

[upperhappy]

Mr. Cothran,

I am previewing the Traditional Logic DVDs this summer in preparation to teach it to my 7th grade son. I am having a wonderful time learning through your clear and well-laid out curriculum. I have also read some of the articles posted on the memoria press web site. In one on Logic and Math, you stated that Modern Logic, first posited by Bertrand Russell, is easily recognizable because of its forms, such as the Venn Diagram, which are widely in use today. I have just finished the 8th chapter of Traditional Logic I where you discuss distributed and undistributed terms and I think you are also making use of Venn Diagrams. These are very helpful to visualize the concept, but I am wondering why you clumped them with Modern Logic and yet use them in the Traditional Logic presentation. Perhaps I am not versed in exactly what the definition of a Venn Diagram is. Any insights you can offer would be most appreciated.

Thanks

Jenny
