===Metaphilosophy and science===
Broad distinguished between critical philosophy and speculative philosophy. He described critical philosophy as analysing "unanalysed concepts in daily life and in science" and then "expos[ing] them to every objection that we can think of". While speculative philosophy's role is to "take over all aspects of human experience, to reflect upon them, and to try to think out a view of Reality as a whole which shall do justice to all of them".<ref name="spec">{{cite book |last=Broad |first=C.

One aspect of critical philosophy was the Principle of Exceptional Cases, whereby everyday concepts are considered in highly abnormal cases, so as to "clear up the meaning" of a concept.<ref name="spec"/>

Broad saw philosophy and science as supplemental to one another. Scientists who ignore philosophy expose themselves to a "danger to which the natural scientist is peculiarly liable. The extraordinary success of physics and chemistry within their own sphere tempts men to think that the world is simply a physico-chemical system". Whereas philosophers who ignore science are ignoring properties which are "very pervasive" and can shed light on things.<ref name=spec/> 

In terms of empirical propositions Broad distinguished between inspective empirical propositions which he defined "one which asserts of some particular existent with which the mind is acquainted at the time some property which the mind can notice by inspection to belong to it" and inferred empirical propositions which are "derived from a number of perceptual propositions either directly by pure inductive generalization, or indirectly by deduction from one or more inductive generalizations".<ref name=spec/>
