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. It is only through genuine experience and mastery of a single subject that one can appreciate the depth and breadth of knowledge, leading to a more profound recognition of one's limitations.
In practice
This quote is perfect for a discussion about the importance of humility in education.
It has always seemed to me extreme presumptuousness on the part of those who want to make human ability the measure of what nature can and knows how to do, since, when one comes down to it, there is not one effect in nature, no matter how small, that even the most speculative minds can fully understand.

The human mind cannot create anything. It produces nothing until having been fertilized by experience and meditation; its acquisitions are the germs of its production.
Rising early and scorning laziness, remaining calm in time of strife, faultless in conduct and clever in actions. One like this will be praised.
A Johns Hopkins doctor says that 'we do not know why it is that the worriers die sooner than the non-worriers, but that is a fact.' But I, who am simple of mind, think I know we are inwardly constructed, in nerve and tissue and brain cell and soul, for faith and not for fear. God made us that way. Therefore, the need of faith is not something imposed on us dogmatically, but it is written in us intrinsically. We cannot live without it. To live by worry is to live against Reality.
As far as I remember, even younger than eight, I have always been guided by reason. Not cold reason, but that which leads to the truth, to the real, and to sane Justice.
