Practical Philosophy - I and Self

Philosophy is practical because some of the concepts that have been proposed could be used in our daily life or learn more about ourselves, but there are some concepts that we wouldn't apply in our daily life like the concept of existentialism (there is no God - makes our existence meaningless OR the concept of everything is in the mind). Philosophy is like math, the basics like multiplication, addition, etc... we use these daily, but if we go to a different area of math, like derivatives, it is not exactly practical anymore. We wouldn't use this in our daily life. In Plato's Euthyphro, Socrates used philosophized with Euthyphro on what the definition of piety is so that he could apply it to his prosecution.

The "I" is the unity of your body and soul. The Self are only accidents that happened in your life. When you were born, school you attended, the people you met, etc.. It means that your actions do not define your true identity. It would lead us to question ourselves, our existence, our purpose. The I and the Self are completely different things. When we die, the "I" perjures, it either remains the same or changes into another effect. Birth to death is a time of possessing, having, becoming of self.

Our Self is just a complex idea. The 'self' is consistently changing day by day by the experiences we have. Each day impacts who we are so there is no definite "self" for a single person.
