The human race is a herd. Here we are, unique, eternal aspects of consciousness with an infinity of potential, and we have allowed ourselves to become an unthinking, unquestioning blob of conformity and uniformity. A herd. Once we concede to the herd mentality, we can be controlled and directed by a tiny few. And we are.
David Icke

We herd sheep, we drive cattle, we lead people. Lead me, follow me, or get out of my way.
George S. Patton

We are the most amazing creatures that this world has ever produced, but we seem to also have this herd mentality; we seem to be the most stupid, also.
Vivienne Westwood

The dissenter is every human being at those moments of his life when he resigns momentarily from the herd and thinks for himself.
Archibald MacLeish
