The whole field is thus divisible into regions (each a confluent) such that each region contains one and only one state of equilibrium or cycle, to which every line of behaviour in it eventually comes. The chief pro- perty of a confluent is that the representative point, if released from any point within it, (a) cannot leave the confluent, (b) will go to the state of equilibrium or cycle, where it will remain so long as the parametric conditions persist. The division of the whole field into confluents is not peculiar to machines of special type, but is common to all systems that are state-determined and that have more than one state of equilibrium or cycle. Habituation 14/3. Consider now what will happen if a polystable system be subjected to an impulsive (S. 6/5) stimulus S repetitively, the stimulus being unvarying, and with intervals between its applica- tions sufficiently long for the system to come to equilibrium before- the next application is made. By S. 6/5, the stimulus S, being impulsive, will displace the representative point from any given state to some definite state. Thus the effect of S (acting on the representative point at a state of equilibrium by the previous paragraph) is to transfer it to some. Figure 14/3/1 : Field of system with twelve confluents, each containing a state of equilibrium (shown as a dot), or a cycle (X at the left). The arrows show the displacements caused by S when it is applied to the representative point at any state of equilibrium or on X. 185.
