The windowing system for AmigaOS. Intuition controls mouse and keyboard input,
provides gadget, menu and requester primitives, provides multiple, overlapping,
depth-sortable windows, and the facility for multiple displays (possibly with
different display properties) called screens.

Intuition used the Amiga's amazingly sweet message passing kernel "exec" as the basis for its message passing/event oriented needs by extending the basic execsystem with intuition specific messages for events like window open, window close, mouse move etc.

Intuition was largely designed by R. J. Mical whose previous claim to fame was the righteously great arcade game Sinistar. His great sense of humor pervades the design with API calls like GimmeZeroZero() etc.

Writing code for Intuition was a dream. Everything made sense and was well documented in the Amiga's Rom Kernel Manual or RKM.

Ah, for the good old days :)

In the system of transcendental philosophy that Kant presents in Critique of pure reason, an 'intuition' is a representation of an individual entity. It is to be distinguished from a concept. Kant's German term is "Anschauung", which is a translation of the Latin technical term "intuitio". Both words literally mean "looking-upon", denoting an instance of beholding something, or as we might say today, a perspective on something.

All of our intuition comes to us via the senses. In classical philosophy, that means that it must be a passively received impression, or a datum (which is Latin for "given"). An intuition gives an appearance of a thing to us. The senses, for Kant, include the five classical "outer senses", and also an "inner sense" whereby we can perceive our own thoughts and feelings. Kant describes intuition as a "manifold", and it seems likely that this means it's a confluence of sensible details, like colors, sounds, textures, odors, etc., distributed for us in space and time. All of these sensibilia are given directly to us by the object we apprehend.

An intuition is not yet a cognition. Intuition is prior to our identification of discrete things in our environment. Cognition requires concepts as well as intuitions. Intuition gives us the inarticulate "this, something", which we must then interpret through concepts. Even our "inner sense", the sense we have of our own thoughts and feelings, must be interpreted. Cognition requires intuition in order for it to refer to actually existing things.
