Their vain presumption of knowing all can take beginning solely from their never having known anything; for if one has but once experienced the perfect knowledge of one thing, and truly tasted what it is to know, he shall perceive that of infinite other conclusions he understands not so much as one.
Interpretation
Knowledge is vast, and recognizing one's limitations is essential for true understanding.
This quote emphasizes the importance of humility in the pursuit of knowledge. Galileo Galilei suggests that those who presume to know everything are often ignorant, as true understanding brings awareness of the vastness of what one does not know.

When you eventually see through the veils to how things really are, you will keep saying again and again, this is certainly not like we thought it was.
Knowledge is like a knife. In the hands of a well-balanced adult it is an instrument for good of inestimable value; but in the hands of a child, an idiot, a criminal, a drunkard or an insane man, it may cause havoc, misery, suffering and crime.
