Man would not be free if he knew no truth at all, and in the same way he would not be free and would not even have any idea of freedom if the whole truth which was to guide him in life had been revealed once for all to him in all its purity without any admixture of error.

Context

“Man is certainly not free if we imagine him stationary, and if we forget that the life of a man and of humanity is nothing but a continual movement from darkness into light, from a lower stage of truth to a higher, from a truth more alloyed with errors to a truth more purified from them. Man would not be free if he knew no truth at all, and in the same way he would not be free and would not even have any idea of freedom if the whole truth which was to guide him in life had been revealed once for all to him in all its purity without any admixture of error. But man is not stationary in regard to truth, but every individual man as he passes through life, and humanity as a whole in the same way, is continually learning to know a greater and greater degree of truth, and growing more and more free from error.” source
