Everything has some value for itself, for others, and for the whole. This characterizes the meaning of actuality. . . . Existence, in its own nature, is the upholding of value intensity. Also, no unit can separate itself from others, and from the whole. And yet each unit exists in its own right. It upholds value intensity for itself, and this involves sharing value intensity with the universe.
– Alfred North Whitehead, Modes of Thought
