Every thinking human being tries to build his or her worldview from the store of his or her own experiences or by drawing upon one's reasoning powers or by drinking from the fount of existing wisdom and knowledge. Every human being has a personal philosophy of life and existence even if it were not as sophisticated as that of, say, Bertrand Russell.
Shakespeare has memorably stated: "There are more things in heaven and Earth,..., than are dreamt of in your philosophy." There may come a time in one's life when this worldview gets shattered and one desperately clings to some beliefs, any beliefs. As they say, Nature abhors a vacuum. Some may become devoutly religious, some may become atheists or agnostics, some may find solace in, say, Spinoza's philosophy or Nietzsche's philosophy.
