From the Gentle Action website:

In his new book Gentle Action: Bringing Creative Change to a Turbulent World Peat argues that while individuals, organizations or governments take action or give aid, often from the best of motives, it is sometimes the case that such action is disruptive and damaging to a community, economy or environment. The reasons are that in some many cases plans and policies do not take into account the complexity and delicate nature of the systems that surround us. Moreover the nature of the organization that attempts to bring about positive change may be more rigid than the system it seeks to alter. In addition so often the organization is now working from within the system but imposing change from outside.

The solutions proposed in the book are that new forms of “gentle action” are needed, actions which begin from within the system in question and emerge in creative ways.. These may range from projects on an international scale to a simple action by an individual. Such actions generally flow from what Peat has termed “creative suspension” -- that temporary pause when we listen and learn what the system has to teach us before taking action.

F. David Peat has dicussed his book on youtube:

And there are several essays about Gentle Action found on the library section of the Gentle Action website.

Drawing on modern physics, chaos theory, perception and learning theory, and many other sources, F. David Peat has put together a notion of Gentle Action.  Pointing out the mechanistic error of trying to reduce or abstract a system down to mere parts, and referencing heavily non-linear systems, Gentle Action appears to be a way of interacting and affecting change with what you see based on a perception of the totality of the situation, which of course includes yourself and thought in it.  At times it seems that F. David Peat is equating intelligence with Gentle Action and at other times it appears that Gentle Action becomes an elucidation on how to clear the way so that intelligence can operate.  One of the key features of Gentle Action is creative suspension, an act through which one’s normal reactions and reflexes are suspended in view to be seen and attended to.  Usually these reflexes just arc out and cause all kinds of trouble and confusion.  When they are held in suspension one has a greater opportunity to learn about them and perceive them.  Along with the notion of creative suspension, F. David Peat draws from choas theory, modern physics, Bohmian non-machanics, and other related areas to show how conventional ideas and worldviews have been distorting us and Gentle Action is attempt to give us a map that will allow us to interact with complex systems in a more coherent manner.  F. David Peat also relies on the notion and metaphor of non-locality which further puts nails into the coffin of a control/hierarchical paradigm of approaching a problem that has an irreducible complexity to it.
