Certain words in the course of long use gather so many strange connotations that they almost cease to mean anything at all. Such a word is imagination. This word is made to serve all manner of ideas, some of them directly opposed to one another. Fancy, thought, hallucination, suspicion: indeed, so wide is its use and so varied its meanings, the word imagination has no status nor fixed significance. For example, we ask a man to "use his imagination", meaning that his present outlook is too restricted and therefore not equal to the task.
