All around me insisted that my doubts proved only my own ignorance and sinfulness that they knew by experience they would soon give place to true knowledge and an advance in religion and I felt something like indecision.

It is no good to try to stop knowledge from going forward. Ignorance is never better than knowledge.

Is there anything science should not try to explain? Science is knowledge and knowledge is power - power to do good or evil. Sometimes ignorance is bliss.

One of the greatest joys known to man is to take a flight into ignorance in search of knowledge.

Every mind was made for growth for knowledge and its nature is sinned against when it is doomed to ignorance.

Doubt is the middle position between knowledge and ignorance. It encompasses cynicism but also genuine questioning.

If they exert it not for good they will for evil if they advance not knowledge they will perpetuate ignorance.

Fullness of knowledge always means some understanding of the depths of our ignorance and that is always conducive to humility and reverence.

There are in fact two things science and opinion the former begets knowledge the later ignorance.

Our knowledge is a receding mirage in an expanding desert of ignorance.
