Until you understand a writer's ignorance, presume yourself ignorant of his understanding.

Ignorance seldom vaults into knowledge, but passes into it through an intermediate state of obscurity, even as night into day through twilight.

In wonder all philosophy began, in wonder it ends, and admiration fill up the interspace; but the first wonder is the offspring of ignorance, the last is the parent of adoration

Wisdom and understanding can only become the possession of individual men by travelling the old road of observation, attention, perseverance, and industry.

Talk of the devil, and his horns appear.

Pretending too much understanding may often lead to ignorance … and ignorance is injurious for any relationship, infact for anything… So don’t compel people to understand you a much more than their threshold.
