The act of designing involves envisaging the production of tangible items While intuition? is generally considered to be a "sensitive" type of perception&sbquo it is really a cognitive ability that directly comprehends the whole and its essence&sbquo Ever since Plato's "intuition of idea&sbquo" cognition theory on intuition has been a subject of philosophical discussion. Originally&sbquo the Japanese word chokkaku was used to translate "intuition" (English and French) when illustrating Western thought&sbquo but it was gradually replaced by the word chokkan. "Intuition" comes from the Latin word intueri meaning "to stare or meditate." The German word anschauung is also composed of the prefix an meaning "approach or contact" and schauen meaning "the act of internationally seeing something "That is&sbquo both "intuition" and anschauung represent ways we think about "knowing." It is the same with the Japanese word chokkan&sbquo which represents direct knowledge that does not rely at all on deduction&sbquo speculation&sbquo or hearsay. White a kind of "hunch" or "foreknowledge" is also called "intuition" (chokkan)&sbquo it involves the problem of whether it was perceived through direct contact with the object of that knowledge. This was put in order by Kant as the "diversity of intuition." This means that as long as we try to know something about an individual thing in the world of reality as an a priori proposition&sbquo and not one based on complete knowledge&sbquo we cannot play down intuitive perceptions. Regarding the intuition of the designer&sbquo in particular&sbquo it is perhaps possible to discuss it based on Husserl's "essential Intuition" and Bergson's "time and sustenance." This is because the designer's intuition is a perceptive ability made possible by direct and straightforward perception that can develop from the knowledge "to present" to knowledge "to verbalize&sbquo" as foreknowledge that grasps something without the assumption of language as its base.
