The vision statement of the Wikimedia Foundation describes our dreams, hopes and ambitions; our most radical conception of our organization and community — 20, 50, 100 years from today. This is the publicly editable version. Please keep this notice intact, and try to find consensus for changes. You are also encouraged to create forks if necessary, and link them from here.

Imagine a universe in which every single sentient being can freely share in the sum of all knowledge. That's our commitment.
