### Famous quotes containing the word matrix:

““The *matrix* is God?”

“In a manner of speaking, although it would be more accurate ... to say that the *matrix* has a God, since this being’s omniscience and omnipotence are assumed to be limited to the *matrix*.”

“If it has limits, it isn’t omnipotent.”

“Exactly.... Cyberspace exists, insofar as it can be said to exist, by virtue of human agency.””

—William Gibson (b. 1948)

“As all historians know, the past is a great darkness, and filled with echoes. Voices may reach us from it; but what they say to us is imbued with the obscurity of the *matrix* out of which they come; and try as we may, we cannot always decipher them precisely in the clearer light of our day.”

—Margaret Atwood (b. 1939)

“In all cultures, the family imprints its members with selfhood. Human experience of identity has two elements; a sense of belonging and a sense of being separate. The laboratory in which these ingredients are mixed and dispensed is the family, the *matrix* of identity.”

—Salvador Minuchin (20th century)
