Recognizing that many of the clothes are blue, while other are white or black, or that some of them are for the upper body, while others are for the legs, is an example of analysis. Abstraction is the process by which we determine to use only one of the many ways we could categorize something. In our own wardrobe, we use abstraction when we decide, for instance, to use colors as a category to organize it. Intellectual comprehension is when our mind makes a representation of objects from a characteristic common among them. Generalization is the process in which we identify the universality and necessity of the concept.
Universality means that a concept can be applied in the same way to anything in the category.
For example, anything we own that is a piece of clothing and that is white will be stored in our whites drawer. Necessity means that in order for one object to be considered in a category, it has to have all of the essential characteristics we have determined for that category. For example, nothing that is not ours, that is not a piece of clothing, or that is not white will be in our whites drawer. There are also some concepts that are a little more difficult to define.
