28 Critical Reflections: random 1 t0 7
Reflection can be used for observing and/or modifying program execution at runtime. A reflection-oriented program component can monitor the execution of an enclosure of code and can modify itself according to a desired goal related to that enclosure.[6]
The inside of River Form is not reminiscent of something formed by the flow of water. There are angles and worked surfaces that suggest deliberate, mindful workings; there are circles …[4]
But the first thing to make clear is that a specular reflection cannot be taken as a sign if one follows the definition given in this book. Not only can it not be properly called an image (since it is a virtual image, and therefore not a material expression) but even granted the existence of the image it must be admitted that it does not stand for something else:on the contrary it stands in front of something else, it exists not instead of but because of the presence of that something: when that something disappears the pseudo-image in the mirror disappears too.[3]
The image in a mirror is not a sign for it and cannot be used in order to lie (if not by producing a false object to be reflected, but in this case what stands for the supposed object is the false body, not its reflection).[3]
Terrific contrast between the strong, tactile sculptures and the exuberance of the foliage and flowers. Apart from one or two pieces marked Do not Touch, you can touch and stroke the sculptures in the garden: take advantage, it's quite an experience.[8]
