“Whenever you see a sweeping statement that a tremendous amount can come from a very small number of assumptions, you always find that it is false. There are usually a large number of implied assumptions that are far from obvious if you think about them sufficiently carefully.”

—  Richard Feynman

“You can ask the question about these ancient topics, such as perfect numbers and amicable numbers… and ask, are these good problems… I'd like to give a small amount of evidence… that they are… [S]tudying them helped us develop all of elementary number theory and from elementary number theory we developed the rest of number theory, and also you can argue that from elementary number theory came algebra..”

“Most of our notions about the world come from a set of assumptions which we take for granted, and which, for the most part, we don't examine or question. We bring these assumptions to the table with us as a given. They are so much a part of who we are that it is difficult for us to separate ourselves from them enough to be able to talk about them. We do not think these assumptions, we think from them.”

“It is a common fallacy to believe that the law of large numbers acts as a force endowed with memory seeking to return to the original state, and many wrong conclusions have been drawn from this assumption.”

“Assumptions are dangerous things to make, and like all dangerous things to make--bombs for instance, or strawberry shortcake--if you make even the tiniest mistake you can find yourself in terrible trouble. Making assumptions simply means believing things are a certain way with little or no evidence that shows you are correct, and you can see how this can lead to terrible trouble. For instance, one morning you might wake up and make the assumption that your bed was in the same place that it always was, even though you would have no real evidence that this was so. But when you got out of your bed, you might discover that it has floated out to sea, and now you would be in terrible trouble all because of the incorrect assumption that you'd made. You can see that it is better not to make too many assumptions, particularly in the morning.”

“On the most usual assumption, the universe is homogeneous on the large scale, i. e. down to regions containing each an appreciable number of nebulae. The homogeneity assumption may then be put in the form: An observer situated in a nebula and moving with the nebula will observe the same properties of the universe as any other similarly situated observer at any time.”

Context: If you want to find Cherry-Tree Lane all you have to do is ask the Policeman at the cross-roads. He will push his helmet slightly to one side, scratch his head thoughtfully, and then he will point his huge white-gloved finger and say: "First to your right, second to your left, sharp right again, and you're there. Good-morning."
And sure enough, if you follow his directions exactly, you will be there — right in the middle of Cherry-Tree Lane, where the houses run down one side and the Park runs down the other and the cherry-trees go dancing right down the middle.
If you are looking for Number Seventeen — and it is more than likely that you will be, for this book is all about that particular house — you will very soon find it.
