“The philosopher must teach these pupils [French students] that it is far less essential to understand nature than to enjoy and respect its laws; that these laws are both wise and simple; that they are written in all human hearts, and that one need merely question a heart in order to appreciate its impulses.”

Context: It became clear to me that simply caring is not enough. To drive real progress, you have to change both hearts and laws. You need both understanding and action.

Context: !-- We would cease to exist if removed from the laws of nature. For instance, we would be totally unable to maintain stability on the surface of the earth without the force of gravity. --> Only those with their eyes open to the world of nature are capable of uncovering its truth. Everything springs from a sense of gratitude toward nature. Aikido, though praised as a healthful system of self-defense techniques, would be nothing apart from the laws of the great universe. The martial way begins and ends with courtesy, itself an attitude of thankfulness to and reverence for nature. To be mistaken on this basic point is to make of the martial arts no more than weapons of injury and death.
The very name Aikido indicates its dependence on the laws of nature, which we term ki. Aikido means the way to harmony with ki. That is to say, Aikido is a discipline to make the heart of nature our own heart, to understand love for all things, and to become one with nature. Techniques and physical strength have limits; the great way of the universe stretches to infinity.

Language Education in a Knowledge Context (1980)
Context: Definitions, like questions and metaphors, are instruments for thinking. Their authority rests entirely on their usefulness, not their correctness. We use definitions in order to delineate problems we wish to investigate, or to further interests we wish to promote. In other words, we invent definitions and discard them as suits our purposes. And yet, one gets the impression that... God has provided us with definitions from which we depart at the risk of losing our immortal souls. This is the belief that I have elsewhere called "definition tyranny," which may be defined... as the process of accepting without criticism someone else's definition of a word or a problem or a situation. I can think of no better method of freeing students from this obstruction of the mind than to provide them with alternative definitions of every concept and term with which they must deal in a subject. Whether it be "molecule," "fact," "law," "art," "wealth," "gene," or whatever, it is essential that students understand that definitions are hypotheses, and that embedded in them is a particular philosophical, sociological, or epistemological point of view.
