“The stability of the internal environment is the condition for the free and independent life.”
Claude Bernard’s statement about the ‘milieu intérior’.
The starting point for ‘A General Theory of Behaviour’ is Claude Bernard’s ‘dangerous idea’, quoted above, the concept of the ‘milieu intérior’. This idea was put on the back burner for several decades because nobody quite knew what to do with it. It looked too dangerous.

Then, in the early Twentieth Century it was taken up by J.S. Haldane, C.S Sherrington, J. Barcroft and a few others. In 1926 the concept gained currency when Harvard physiologist Walter B Cannon coined the term homeostasis for milieu intérior. In Cannon’s view, his book The Wisdom of the Body had presented a modern interpretation of vis medicatrix naturae, the healing power of nature posited by Hippocrates. Cannon also believed he had shown how the automatic function of homeostasis freed the brain for the more intellectual functions of intelligence, imagination and insight.
At this point, the homeostasis story picks up apace. Add to the mix of Bernard and Cannon, spice the pot with the work of Wiener (1948), Von Bertalanffy (1968) and season it with the work of biologist J Scott Turner (2017) and we have a ‘stew’ to die for. As the contents of the pot bubble and coalesce, we sense that homeostasis is not only advantageous for any living system, but it could even be the defining characteristic of life itself.
At every level of existence, from the cell to the organism, from the individual to the population, and from the local ecosystem to the entire planet, homeostasis is a drive towards stability, security and adaptation to change. In an infinite variety of forms, omnipresent in living beings, is an inbuilt function with the sole purpose of striving for equilibrium, not only in the milieu intérieur but in the milieu extérieur also.
We take a gigantic leap…but that’s why we are here – even if we feel we are at the edge of a cliff – we must go for it…
On the other side of Bernard’s scientific coin, we imagine we find the following:
“The stability of the external environment is the condition for the free and independent life.”
By changing a single word ‘internal’ to its antonym, we create a whole new theoretical perspective for the Science of Behaviour. Voila – “A General Theory of Behaviour”. Striving for balance and equilibrium is the guiding force in all we – and all other conscious beings – do, think and feel. This newly defined homeostasis deserves a descriptive name: “Reset Equilibrium Function” (REF).
All organisms automatically regulate essential physiological functions by homeostasis and it is a matter of everyday observation that drives are maintained in equilibrium by comportment, e.g. eating, drinking, fornicating, sleeping, excreting, etc. This type of homeostasis has been established since the time of Bernard. Far more than this, and as a matter of routine, without any special reflection in most instances, all conscious beings reconcile discrepancies among their thoughts, behaviours, and feelings and in the differences with those with whom they have social relationships. Conscious organisms strive to achieve their goals while maximizing cohesion and cooperation with both kith and kin and, at the same time, striving to take away or to minimize the suffering and pain of others. [Auxiliary Proposition, AP 001].
The goal is to minimize all forms of eyeball-to-eyeball confrontation and tooth-and-claw competition and to live in a culture where the thriving of all is in the self-interest of every individual. The hypothesis has been described by Antonio Damasio thus: “cultural instruments first developed in relation to the homeostatic needs of individuals and of groups as small as nuclear families and tribes. The extension to wider human circles was not and could not have been contemplated. Within wider human circles, cultural groups, countries, even geopolitical blocs, often operate as individual organisms, not as parts of one larger organism, subject to a single homeostatic control. Each uses the respective homeostatic controls to defend the interests of its organism” (Damasio, 2018, p. 32).
Whether we are aware of it or not, the REF is omnipresent, wherever we go and whatever we are doing. The process is not something we normally focus attention on, the process through which our behavioural systems are perpetually striving to maintain balance, safety and stability in our physical and social surroundings. Competing drives, conflicts, and inconsistencies all can pull the flow of events ‘off balance’, triggering this innate striving to restore equilibrium. The majority of people for the majority of time strive to calm and quieten local disturbances of equilibrium rather than to exacerbate them. [AP 002]. It is not a battle that we can always win; there is always the possibility of instability, error, calamity or catastrophe even.
There are abundant links to other theories inside and outside of Psychology. Piaget’s notion of equilibration was concerned with the attempt to balance psychological schemas when new information is encountered. In equilibration, children accommodate new information by changing their psychological schemas in a process of assimilation. This same idea applies to other psychological domains when there is a departure from a set range of equilibrium. Advocates of Buddhist philosophy, for example, the Dalai Lama, have identified a need for inner peace.
Body and mind continuously regulate and control many domains and levels simultaneously, with multiple adjustments to voluntary and involuntary behaviour guided by two types of homeostasis: Type I – inwardly striving or physiological homeostasis, H[Φ], and Type II – outwardly striving or psychological homeostasis, H[Ψ]. Physiological regulation involves drives such as hunger, thirst, sex, elimination and sleep. Influenced by Cannon, Clark Hull (1943) suggested a drive theory of regulatory mechanisms in which an organism can only rest when it is in a state of equilibrium. When a need such as hunger or thirst develops, the organism engages in need-satisfying behaviour. However, ‘drive’ can be mental as well as physical so that misery, fear and worry – often lumped together as ‘stress’ – create a state of unrest that prevents calmness, relaxation and sleep. Whenever we feel unrest, there is a need to ‘press the reset button’ and restore equilibrium. The ‘Reset Equilibrium Function’ (REF) operates across all behavioural systems and processes of relevance to the Science of Psychology.
A General Theory of Behaviour pivots on the Reset Equilibrium Function (or ‘REF’) by integrating the principle of homeostasis with our understanding of psychological processes and behaviour. We employ systems theory with cyclical negative feedback loops as a central feature. Feedback loops in Cybernetics and Control Theory mirror homeostasis within Biology and Neuroscience. Claude Bernard’s ‘milieu intérnal’, Cannon’s (1932) ‘homeostasis’, Wiener’s (1948) Cybernetics and von Bertalanffy’s (1968) general systems theory all converge toward the ubiquitous role of feedback in self-regulating systems. Psychologists have employed control theory as a conceptual tool for large areas of Psychology (e.g. Carver and Scheier, 1982) and, notably, one objective of control theory has been to provide a “Unified Theory of Human Behaviour”.
A General Theory of Behaviour employs systems of homeostasis in networks of interconnected processes with values that are reset by the REF. This hypothesis is founded on principles in Biology, Engineering and Cybenetics which have compelling isomorphisms with phenomena in Psychology, the subject of this book.
The Reset Equilibrium Function extends the reach of homeostasis to a general control function that automatically restores psychological processes to equilibrium and stability. The REF is triggered when any processes within a system strays outside of its set range. The REF is innate and can exist only in conscious organisms, which all have Type I and II homeostasis. Non-conscious organisms have one type of homeostasis (Type I).
Figure 1.1 shows Type II homeostasis in a system of four processes, each with its own set range, making a series of resets. Any set of processes such as the four in Figure 1.1 is a sub-set of thousands of interconnected processes responsible for coding, communicating and controlling inside the body and the brain. Any process can be connected to hundreds or thousands of others in one huge lattice structure. Potentially any single one of these processes can push any other process out of its set range requiring it to reset. When any process resets, a ‘domino-effect’ is possible when other interconnected processes require a reset also. The two types of homeostasis work in synergy. Psychological and physiological processes operate in tandem to maximize equilibrium for each particular set of functions. [AP 003].
Many examples of the REF featured in this book have a similar structure to that shown in Figure 1.1. However, there is no restriction on the number of participating processes or interconnected networks.

My main objective here is to demonstrate that the REF is relevant to numerous psychological functions. These include functions where frequent reset is a condition for stability, e.g. cognition, affect, chronic stress, and subjective well-being, and also where out-of-control behaviour, such as addiction or insomnia, is in need of correction. For all psychological functions, conscious awareness of the state of equilibrium being preserved is not necessary, e.g. subjective well-being. However, when there is goal to change behaviour, conscious awareness of the goal and full engagement of resources are necessary preconditions for purposeful striving, e.g. addiction to alcohol.
In Psychology, biological approaches automatically fall under the suspicion that material reductionism is required. This suspicion is widespread among psychologists who are anti-reductive. With good reason, mind and behaviour are viewed as having properties that extend beyond ‘cogs and flywheels’ or other physico-chemical energy exchanges. We do not doubt the basic ‘clockwork’ model of homeostasis is the dominant one; witness the frequent use of the domestic heating thermostat as the prototypical example of homeostasis in Biology, Physiology and Psychology textbooks. However, the ‘clockwork’ approach is a simplistic caricature and the hypothesis that all behaviour is reducible to physico-chemical reactions is robustly rejected:
Principle I (Agency): The voluntary behaviour of conscious organisms is guided by universal striving for equilibrium with purpose, desire and intentionality.
Following G.E.M. Anscombe, we assert that agents act intentionally if they know what they are doing, i.e. they are aware of the purpose of the act and the reasons for doing it. Type 2 homeostasis, which is associated with the REF, falls into this category. In arguing that homeostasis (Type II) is intentional and purposeful, we adopt two non-reductionist principles, holism and critical realism. In applying the General Theory it is never necessary to assume that mental processes and behaviours are reducible to physico-chemical reactions. We only require that the mind/body system as a whole can be studied using objective methods. Von Bertalanffy (1968) sums up the issue thus:
“We cannot reduce the biological, behavioural, and social levels to the lowest level, that of the constructs and laws of physics. We can, however, find constructs and possibly laws within the individual levels. The world is, as Aldous Huxley once put it, like a Neapolitan ice cream cake where the levels-the physical, the biological, the social and the moral universe-represent the chocolate, strawberry, and vanilla layers. We cannot reduce strawberry to chocolate – the most we can say is that possibly in the last resort, all is vanilla, all mind or spirit. The unifying principle is that we find organizational levels. The mechanistic world view, taking the play of physical particles as ultimate reality, found its expression in a civilization which glorifies physical technology that has led eventually to the catastrophes of our time. Possibly the model of the world as a great organization can help to reinforce the sense of reverence for the living which we have almost lost in the last sanguinary decades of human history.”
Von Bertalanffy, 1968, p. 49.
There are connections and overlaps with other theories of motivation. For example, there is almost complete convergence between the General Theory and Stevan E Hofoll’s Conservation of Resources (COR) theory, which holds the basic tenet that “Individuals (and groups) strive to obtain, retain, foster, and protect those things they centrally value.”. Principle I (Agency) concerning the universal striving for equilibrium requires the basic COR tenet to be true or equilibrium could never be attained.
