The document discusses several philosophers' views on the meaning of life and how to attain a meaningful existence. Socrates, Plato, and Aristotle believed happiness requires virtue and contemplation. Nietzsche advocated realizing one's "higher self" by fulfilling noble ideals. Schopenhauer saw life as suffering caused by desires that make us harm each other. Heidegger viewed human existence as "care" shaped by possibilities, facticity, and fallenness. For Sartre, freedom is essential for authenticity while avoiding "bad faith." Jaspers and Marcel both emphasized transcendence but differed in their philosophical methods of reflection.
