by emotions, we know ourselves

So, I passed a long time trying to make evident my virtues (if I had one) and make some conclusions.

I only have the certitude that I have a virtue when I have the correspondent emotion.

If I am a generous person, my emotions are generous. If I am a prudent, I always feeling my attention to feel what surrounds me, feeling certain prudent emotions. And so on.

I can question myself what I am but only have true aswer by examining my emotional side, what emotions do I evoke by this question, or what emotions I am constantly feeling.
