It is so easy to hide our ignorance under such expressions as the plan of creation or unity of design, etc., and to think that we give an explanation when we only restate a fact.

The more one thinks, the more one feels the hopeless immensity of man's ignorance.

Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.

Desire, ignorance, and inequality-this is the trinity of bondage.

Truth is by nature self-evident. As soon as you remove the cobwebs of ignorance that surround it, it shines clear.

The darkest night is ignorance.
