Plagiarism is masquerading another's ideas as your
own. Using a single
source almost always leads to this situation (unless you creatively
reinterpret the single source (==original research!)). You can be
plagiaristic while crediting the work you're plagiarising - depends
how the referencing is done.
If I were to restate a philosopher's critique without incorporating
other critiques or constantly reminding the reader that the critique
is not my own (e.g. "Dennett then goes on to state..."), I risk
plagiarism. This is the case even if I reference the philosopher (here
Dennett) at the end of the essay.

Not if you candidly credit your source for each significant fact or assertion contained in
your article. Just a footnote at the end would not suffice. We expect every significant
fact or assertion to be verifiable by reverence to a reliable source. You may have written
a poor article, but you have not plagiarized.
