You could attach prices to ideas. Some cost a lot some little. ... And how do you pay for ideas? I believe: with courage. - Ludwig Wittgenstein

If you already have a person's love no sacrifice can be too much to give for it; but any sacrifice is too great to buy it for you.

The temporal immortality of the soul of man, that is to say, its eternal survival also after death, is not only in no way guaranteed, but this assumption in the first place will not do for us what we always tried to make it do. Is a riddle solved by the fact that I survive forever? Is this eternal life not as enigmatic as our present one? The solution of the riddle of life in space and time lies outside space and time.

If, for example, you were to think more deeply about death, then it would be truly strange if, in doing so, you did not encounter new images, new linguistic fields.
