of the various sciences. Not all linguistic analysts however define knowledge so narrowly. althougt threy do reject and try to clean up many nonscientific assertions many of them think that we can have knowledge of ethical principles and the like although this knowledge is also experientially derived those who take the narrower view neglect when they do not deny all generalized world views and life views as well as traditional moral philosophy and theology. from this more narrow point of view the aim of philosophy is to expose confusion and nonsense and to clarify the meaning and use of terms in science and everyday affairs.
