 Broad’s theory of perception employs an act-object analysis of sensations. Lest it should be thought that he should be incapable to think of any alternative account it should be noted that he examines such an analysis as early as in 1921. G. F. Stout and H. A. Prichard defended such an alternative (both of whom Broad held in the highest regard). Their account could be considered an early version of the adverbial analysis of sensations. Broad asks us to consider a headache. “It is by no means clear that a headache means a state of mind with a headachy object [i.e. an act with a certain object]; it seems on the whole more plausible to say that that it is just a headachy state of mind” (1921b, p. 392). To have a headache is not to be aware of a headachy object but to feel in a certain  way.[6]  The alternative account claims that this holds mutatis mutandis for any type of sensation. Thus what is described as ‘a sensation of red’ is a unitary state of mind, and strictly speaking not a state which decomposes into an act of sensing and a sensed red patch.
