Existentialism is a way of thinking about life that says it's up to us to give meaning to our lives. We are all born into the world without any meaning or purpose, and it's up to us to create our own. Existentialists believe that we have free will, which means we have the ability to make choices about our lives. But with that freedom comes responsibility. We have to take responsibility for our choices and the consequences that come with them.
Humanism is a belief that focuses on the importance of humans and their individual experiences. It emphasizes the idea that each person has intrinsic value and should be treated with dignity and respect. Humanists believe that people are capable of making their own decisions and living fulfilling lives. They reject the idea that humans are naturally sinful or evil, and instead believe that people are born good and capable of doing good things.
So, when we put existentialism and humanism together, we get a belief system that says we are responsible for creating our own meaning and purpose in life, but at the same time, we should value and respect other people and their experiences. It's important to remember that we are all in this together and that each person's life is valuable and important.
