Existentialism

Unlike tools which are created for a specific purpose, e.g., hammer to drive nails; man's existence is without a meaning or purpose.

Advaita

A physicist would remind us that the things we see "out there" are not ultimately seperate from each other and from us; we perceive them as seperate because of the limitations of our senses. If our eyes were sensitive to a much finer spectrum we might see the world as a continuous field of matter and energy. Nothing in this picture resembles a solid object in our usual sense of the world. The external world of physics has thus become a world of shadows. In removing our illusions we remove the substance, for indeed we have seen that substance is one of the greatest of our illusions.

- Sir Arthur Eddington
