There’s no way to get from the point in Hemm space where we are now, to one that includes pink nerve-gas-farting dragons, following any plausible action principle. Which is really just a technical term for there being a coherent story joining one moment to the next. If you simply throw action principles out the window, you’re granting the world the freedom to wander anywhere in Hemm space, to any outcome, without constraint. It becomes pretty meaningless. The mind...knows that there is an action principle that governs how the world evolves from one moment to the next—that restricts our world’s path to points that tell an internally consistent story. So it focuses its worrying on outcomes that are more plausible...

Then the theory of relativity came and explained the cause of the failure. Electric action requires time to travel from one point of space to another, the simplest instance of this being the finite speed of travel of light... Thus electromagnetic action may be said to travel through space and time jointly. But by filling space and space alone [excluding time] with an ether, the pictorial representations had all supposed a clear-cut distinction between space and time.
James Jeans
There are three principles in a man's being and life, the principle of thought, the principle of speech, and the principle of action. The origin of all conflict between me and my fellow-men is that I do not say what I mean and I don't do what I say.
Martin Buber
A democracy is more than a form of government; it is primarily a mode of associated living, of conjoint communicated experience. The extension in space of the number of individuals who participate in an interest so that each has to refer his own action to that of others, and to consider the action of others to give point and direction to his own, is equivalent to the breaking down of those barriers of class, race, and national territory which kept men from realizing the full import of their activity. These more numerous and more varied points of contact denote a greater diversity of stimuli to which an individual has to respond; they consequently put a premium on variation in action. They secure a liberation of powers which remain suppressed as long as the incitations to action are partial, as they must be in a group which in its exclusiveness shuts out many interests.
John Dewey
Most often, the reason something is "on your mind" is that you want it to be different than it currently is, and yet: you haven't clarified exactly what the intended outcomes is; you haven't decided what the very next physical action step is; and/or you haven't put reminders of the outcome and the action required in a system you trust. That's why it's on your mind.
David Allen
Realism maintains that universal moral principles cannot be applied to the actions of states in their abstract universal formulation, but that they must be filtered through the concrete circumstances of time and place. The individual may say for himself: "Fiat justitia, pereat mundus (Let justice be done, even if the world perish)," but the state has no right to say so in the name of those who are in its care. Both individual and state must judge political action by universal moral principles, such as that of liberty. Yet while the individual has a moral right to sacrifice himself in defense of such a moral principle, the state has no right to let its moral disapprobation of the infringement of liberty get in the way of successful political action, itself inspired by the moral principle of national survival.
