What is the purpose of philosophy or spirituality?
As long as humans live amongst a group of people, community, the environment and exist within the universe, why is philosophy needed? Philosophy helps us to understand the world around us, and helps us to question and re-examine the cultural constructs we live by. Through the process of questioning and re-examining, we're able to incorporate ethics in our daily conducts as a social more, a spoken or unspoken written rule based on values of fairness, equality, and reason.
Philosophy helps us to question science, the mind, all aspects of living.
Spirituality, what are its purposes? Some people chose to live spiritual lives, whether or not they believe in a God or multiple Gods, or no God because spirituality to them is essential, because spirituality gives meaning to everyday existence. You're able to transcend beyond philosophy and science, and actually apply it in every moment of your life. These are all of the subliminal questions wrapped up into one, and spirituality is the art of living the way we choose to based on how we perceive our own realities and the way we conduct ourselves.
