"Two kinds of blindness are easily combined so that those who do not see really appear to see what is not"

This quote by Tertullian speaks to the idea of willful ignorance and the power of understanding. He recommends that 2 kinds of loss of sight can be combined in such a method that those who are not seeing the fact can appear to be seeing something that is not real. This might be analyzed as a warning against the threats of thinking in something that is not real, or of being willfully oblivious of the reality. It might also be analyzed as a commentary on the power of perception and how it can form our understanding of the world. By thinking in something that is not true, we can be quickly misled and controlled. This quote functions as a pointer to be familiar with our own biases and to be available to various perspectives. It is essential to be conscious of our own beliefs and to be going to challenge them in order to gain a better understanding of the world.
