Hello, Marcia,
Interesting paper. I have to admit I've never heard of "abduction", the more or less intuitive acceptance or rejection of hypotheses on the way to explaining the unexplained.

And, I sort of enjoyed finding the below.

"Deduction
After suggesting a plausible hypothesis, the next stage is to refine the hypothesis with logical deduction. Deduction is drawing logical consequences from premises. The conclusion is true given the premises are true also (Peirce, 1868). For instance,

All As are Bs.
C is B.
Therefore, C is A. "

Not necessarily true. For example,

All ravens are crows, this bird is a crow, therefore this bird is a raven.
Doesn't follow and I suspect it was a typo. Sorta fun to find, though.

Thanks again for the instructive post.
