“All that is required for evil to triumph is for good men to do nothing.” Is a rather famous aphorism.

But how do you know that you are a good man? How do you know what you should do?

I use this aphorism and the resultant questions to highlight the importance of preparation. That is of preparing ones mind for struggle and moral quandries through establishing and examining principles.

The establishment and examination of principles is perhaps the most important function of philosophy.
