| Abstract: | This paper uses Category Theory to integrate a nonlinear, nonhomogeneous 
ordinary differential equation system into an input/output representation in 
an attempt to capture the mechanism behind the formation of pure preference in 
humans. The model shows that the human brain belongs to the class of functions 
U ε C2(R3, R). In addition, it shows that there exists an emerging factor, e, 
which is sine qua non for expressing a preference. The factor, e, may be 
associated with ‘judgement’ which, in turn, may neatly subsume 
‘consciousness’, the arrival of new information, and cases of selection under 
risks and uncertainty. |
