If we spoke a different language, we would perceive a somewhat different world.
Mathematics is a logical method. . . . Mathematical propositions express no thoughts. In life it is never a mathematical proposition which we need, but we use mathematical propositions only in order to infer from propositions which do not belong to mathematics to others which equally do not belong to mathematics.
Interpretation
What this quote means
Mathematics serves as a tool for understanding the world rather than as a standalone source of meaning.
In this quote, Ludwig Wittgenstein emphasizes that mathematical reasoning is not an end in itself but a means to connect and infer ideas that are grounded in the non-mathematical aspects of life. He suggests that while mathematical propositions are logical constructs, true understanding comes from applying these constructs to the complexities of human experience and thought, which cannot be encapsulated by numbers or formulas alone.

No one likes having offended another person; hence everyone feels so much better if the other person doesn't show he's been offended. Nobody likes being confronted by a wounded spaniel. Remember that. It is much easier patiently - and tolerantly - to avoid the person you have injured than to approach him as a friend. You need courage for that.
It's impossible for me to say one word about all that music has meant to me in my life. How, then, can I hope to be understood?

My day passes between logic, whistling, going for walks, and being depressed. I wish to God that I were more intelligent and everything would finally become clear to me - or else that I needn't live much longer.

Agitators are a set of interfering, meddling people, who come down to some perfectly contented class of the community and sow the seeds of discontent amongst them. That is the reason why agitators are so absolutely necessary. Without them, in our incomplete state, there would be no advance towards civilization.
Men always talk about the most important things to perfect strangers. In the perfect stranger we perceive man himself; the image of a God is not disguised by resemblances to an uncle or doubts of wisdom of a mustache.

WE ARE DESTROYING OUR COUNTRY - I mean our country itself, our land. This is a terrible thing to know, but it is not a reason for despair unless we decide to continue the destruction. If we decide to continue the destruction, that will not be because we have no other choice. This destruction is not necessary. It is not inevitable, except that by our submissiveness we make it so.
