Well, they would be represented in the brain by neurons, which have a natural ReLU function attached to them. I think they are always non-negative, but the derivative is unbounded, so they can saturate at 0 if someone grows totally uninterestsed in the question of whether they hate or love some particular entity.

Indeed.
This monotonicity (non-decrease in accumulated love and hate) is interesting (it resembles motifs from Scott topology used in denotational semantics).
And this decomposition into positive and negative components which evolve monotonically does resemble motifs in some of my math scribblings...
