Quote by Miguel de Unamuno
For the truth is that our doctrines are usually only the justification a posteriori of our conduct, or else they are our way of trying to explain that conduct to ourselves.
Summary
This quote suggests that our beliefs or doctrines are often formed after we have already taken certain actions or made certain decisions. They serve as a way to rationalize or justify our behavior, or as a means to provide an explanation and understanding for that behavior. In other words, our doctrines frequently act as a reflection of our actions rather than guiding principles that govern them.
