Black and white thinking

Black and white thinking - thinking in all or nothing terms. The world is seen in terms of dichotomies, such as people are either all good or all bad, 100% successful or a failure, strong or weak and so on. Shades of grey do not seem to exist for black and white thinkers. 

In the same way, sfumato represents the end of black-and-white thinking about the world in general. It teaches us that a complex concept (e.g., the concept of a man ) cannot be reduced to a single point (i.e., a single example of a man ). These complexities must be described by using... 

I also have a comment about the trigonal bipyramid vs. square pyramid configurations. Little physical motion of atoms is required to go from one to the other. There can be, I think, a tendency to take symmetry arguments too literally as black and white situations. The full symmetry of these complexes is considerably less than the symmetry one derives just from the arrangements of atoms next to the central ion. I do think it is possible to depend too much on exact symmetry designations. 

Watch the portion of The Wizard of Oz in which the film changes from black and white to color. Explain why you think the film was made in this manner. Discuss the use of black and white and color in other films you have seen (e.g., why do you think that Schindler s List was first filmed in black and white and later filmed in color ). 

North Beach had served for years as home ground for beatnik activities and had become a center for cultural ferment in America. The beats generally favored stark contrasts of black and white, in their dress and in their thinking. They emphasized the role of the Artist and the Bohemian, celebrated blacks as culture heroes, and were politically active against the Bomb. Their style found expression in after-hours poetry and jazz in coffeehouses. Their taste in drugs inclined to pot, speed and heroin. 

Alternatively, think back to the image at the start of the chapter with the black and white balls for another analogy. Remember that the wheel is selective for white balls. Towards the end of the reaction, there are hardly any white balls left and the wheel, which doesn t have perfect selectivity anyway, will find it increasingly hard to pick them out. And if all the white balls have gone, then the wheel, if it continues reacting, will be forced to react with the black balls. This is all bad news for selectivity. If there were another water wheel which was selective for black balls (but delivered them to a separate container) then the concentration of black balls would not increase. 

He also completed three standardized self-report scales before and after therapy. He initially scored 28/63 (moderate depression) on the Beck Depression Inventory and 19/63 (mild anxiety) on the Beck Anxiety. Inventory (Beck and Steer 1987). The Dysfunctional Attitude Scale (Weissman 1979) aims to measure beliefs that predispose to depression (e.g. black or white thinking and perfectionism). His score of 187/240 before CBT was above the typical mean for both controls (113) and depressed individuals (147). 

The whole set of operations produces an axial molecule in which there are four equivalent substituents at either end. The black and white points are at different distances from the axis, and so the radii of the circles drawn to show the relationship between images in Figure 3.6a are different, emphasizing that there are no symmetry-equivalent points at opposite ends of the object. Below the three-dimensional sketch is a plan view of the same structure. For the points at either end of the object, we could also think to introduce vertical mirror planes relating the points to their opposite images within the same terminal group. However, the offset in orientation between the two ends is such that these mirror planes would not be symmetry elements of the object as a whole.
