Things are always more complex than you can envision and it would be foolish to think that they are only as complex as you understand them. It is always a choice to simplify things and this is not necessarily faulty although it does have a way of limiting your overall understanding.
A simple view is what is necessary for understanding a general or basic idea because it is possible to understand the great by understanding the minuscule. However, even the most simple of things in existence have a complex myriad of layers that when understood tell a much deeper and complete story than what they speak to on their surface.
