Abstractions are difficult to grasp for many people—Jean Jacques Rousseau, for example. As Gombrich notes in Visual Thinking, Rousseau said that he could not grasp the idea that the square of a binomial equals the sum of its two terms plus twice their product. Even rendering it mathematically didn't help him much:

What did was the visual representation of squares and rectangles.

The fundamental maxim of professional writing: Give the read control.

Not only can one visualize the abstraction, one can manipulate it.
