None are so old as those who have outlived enthusiasm.
Henry David ThoreauRead
Even the facts of science may dust the mind by their dryness, unless they are ... rendered fertile by the dews of fresh and living truth. Knowledge does not come to us by details, but in flashes of light from heaven.
Interpretation
Scientific facts alone can be dry and uninspiring unless enlivened by deeper truths; understanding comes in moments of insight.
In this quote, Thoreau emphasizes the importance of integrating fresh and vibrant truths into scientific knowledge to make it engaging and meaningful. He suggests that mere details of science can be tedious, and real knowledge often arrives in sudden, enlightening moments that illuminate our understanding.
In practice
This quote can be used in a science class to illustrate the importance of deeper understanding in learning.
None are so old as those who have outlived enthusiasm.
Through want of enterprise and faith men are where they are, buying and selling and spending their lives like servants.
An early-morning walk is a blessing for the whole day.
Have no mean hours, but be grateful for every hour, and accept what it brings. The reality will make any sincere record respectable.
As every season seems best to us in its turn, so the coming in of spring is like the creation of Cosmos out of Chaos and the realization of the Golden Age.
That grand old poem called Winter
The idea that you can ask one question and it makes the point - well, that wasn't how psychology was done at the time.
Chemistry is necessarily an experimental science: its conclusions are drawn from data, and its principles supported by evidence from facts.
I think the appropriate response for a physicist is: 'I do not find the concept of God very interesting, because I cannot test it.'
In science, you can say things that seem crazy, but in the long run, they can turn out to be right. We can get really good evidence, and in the end, the community will come around.
The last thing that man will understand in nature is the performance of his brain.
Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.
