Philosophy: the diverse study of general and fundamental questions about reason, existence, knowledge, values, mind, and language addressing questions such as, “What is real?” and “How do we know anything?”
Worldview: the lens through which we view all of life or in other words, how we make sense of the world and everything happening in it. Basic worldview questions include: How did the world begin? Where did we come from? Why are we here? What is wrong with humanity? How do we fix it? Where do we go when we die?
