I’ve tried to say many times what Stengers says here:
To try to render a philosophical proposition “present” means first of all to try to avoid the form of commentary that is suitable for the exposition of an author’s beliefs, of what he or she thinks. It is to make thought inseparable from the problem of “how to think” that obliges this thought.
This is why I warn people away from philosophy surveys that report the beliefs and outline the arguments of philosophers.
Philosophies are not “belief systems.”
Neither are religions, for that matter.
