William T. Powers (1926-2013) Visionary, collaborator & friend
A theory ahead of its time?
In 1973, William T. Powers published 'Behavior: The Control of Perception'. The book formalised the theory he had been developing since the 1950s, and now it is unifying the physical, life and social sciences. The book is available at livingcontrolsystems.com.
PCT provides a theory about how human beings and other living systems work – how they control what matters to them. Take a look at the video below to get started...
You can also try out a whole range of interesting ways to illustrate perceptual control on Gary Cziko's website.

The idea is simple.
You don’t have to pay for it. It’s for everyone to use.

The Evidence Base for PCT & Mental Health Applications
The current evidence base for PCT, accumulated over the last five decades to the present day, is summarised in a downloadable working document that will be updated regularly pending its publication as a review. Feedback is welcome. A working document of published papers on PCT and its application to mental health is also available here.
