(...) Morpheus warns Neo "Remember, all I'm offering is the truth. Nothing more."

(...)The blue pill will leave us as we are, in a life consisting of habit, of things we believe we know. We are comfortable, we do not need truth to live.

(...)The red pill symbolises risk, doubt and questioning. In order to answer the question, you can gamble your whole life and world on a reality you have never experienced.

(...)Trinity says to Neo "It's the question that drives us, Neo."

(...)However, the choice over the red or blue pills is not solely a choice between whether to question or not, it is a personal choice on the method of discovering the truth.
