According to Wikipedia The meaning of life as we perceive it is derived from our philosophical and religious contemplation of, and scientific inquiries about existence, social ties, consciousness, and happiness.
Many other issues are also involved, such as symbolic meaning, ontology, value, purpose, ethics, good and evil, free will, the existence of one or multiple gods, conceptions of God, the soul, and the afterlife.
Quite a lot to digest!
Here are some quotes on the subject from an eclectic mix of people:
“For me life is continuously being hungry. The meaning of life is not simply to exist, to survive, but to move ahead, to go up, to achieve, to conquer.”
“If there is meaning in life at all, then there must be meaning in suffering.”
-Viktor E. Frankl
“The sole meaning of life is to serve humanity.”
“The meaning of life is contained in every single expression of life. It is present in the infinity of forms and phenomena that exist in all of creation.”
“There is more to life than increasing its speed.”
“Be glad of life because it gives you the chance to love and to work and to play and to look up at the stars.”
-Henry Van Dyke
“I think everybody should get rich and famous and do everything they ever dreamed of so they can see that it’s not the answer.”
