Morpheus in The Matrix:
“It is the world that has been pulled over your eyes to blind you from the truth – that you are a slave. Like everyone else you were born into bondage. Into a prison that you cannot taste or see or touch. A prison for your mind.”
Jean-Jacques Rousseau from his essay “Discourse on the Sciences & the Arts“:
“The mind has its needs just as the body does. The latter are the foundations of society; from the former emerge the pleasures of society. While government and laws take care of security and the well being of men in groups, the sciences, letters, and the arts, less despotic and perhaps more powerful, spread garlands of flowers over the iron chains which weigh men down, snuffing out in them the feeling of that original liberty for which they appear to have been born, and make them love their slavery by turning them into what are called civilised people.”
Both would tell you to free you mind.
