Question

When citing a scholarly article, where the author cites a well known book, does it matter if I cite the original source (the book the secondary material is looking at) or the scholarly article? In other words, if I am quoting Cassier, but not the author of the scholarly article at the moment, does it matter if I cite Cassier or the person publishing the scholarly journal?

Answer 1

...strictly speaking it'll be a safer bet to reference Cassier, even though it may be well-known, as you'll be open to a charge of plagiarism otherwise... speak with your academic advisers/tutors to see what your school/department/college's policy is on the matter :)

Answer 2

I would reference who exactly said the quote, not who is also referencing the quote. However if that quote is being used to make a point and you want to include the point from the scholarly article, reference the scholarly article as well as the original source.
