Beyond the biological, the psychological and the sociological take over by
introducing degrees of freedoms in the expectation. One can see that from
the bifurcation diagram for the logistic map and its anticipatory
equivalents below:

  <http://users.fmg.uva.nl/lleydesdorff/temp/index_files/image001.gif>

x(t+1) = a x(t) [1 - x(t)]

The psyche is modeled as a weakly anticipatory system using the incursive
equivalent of the logistic equation:

x(t+1) = a x(t) [1 - x(t+1)]

The social system as a strongly anticipatory one using a hyperincursive
equivalent:

x(t) = a x(t+1) [1 - x(t+1)}

Since this equation is quadratic, one obtains two solutions at each time
step. By taking turns (in terms of the sign of the equation) the social
system develops a trajectory in real time within this field of
possibilities.
