“Each individual fact, taken by itself, can indeed arouse our curiosity or our astonishment, or be useful to us in its practical applications. But intellectual satisfaction we obtain only from a connection of the whole, just from its conformity with law.”

Context: Every great deed of which history tells us, every mighty passion which art can represent, every picture of manners, of civic arrangements, of the culture of peoples of distant lands or of remote times, seizes and interests us, even if there is no exact scientific connection among them. We continually find points of contact and comparison in our own conceptions and feelings; we get to know the hidden capacities and desires of the mind, which in the ordinary peaceful course of civilised life remain unawakened.
It is not to be denied that, in the natural sciences, this kind of interest is wanting. Each individual fact, taken by itself, can indeed arouse our curiosity or our astonishment, or be useful to us in its practical applications. But intellectual satisfaction we obtain only from a connection of the whole, just from its conformity with law.

Context: Fundamentally, our chief problem may be summed up as the effort to make men as nearly as they can be made, both free and equal; the freedom and equality necessarily resting on a basis of justice and brotherhood. It is not possible, with the imperfections of mankind, ever wholly to achieve such an ideal, if only for the reason that the shortcomings of men are such that complete and unrestricted individual liberty would mean the negation of even approximate equality, while a rigid and absolute equality would imply the destruction of every shred of liberty. Our business is to secure a practical working combination between the two. This combination should aim, on the one hand to secure to each man the largest measure of individual liberty that is compatible with his fellows getting from life a just share of the good things to which they are legitimately entitled; while, on the other hand, it should aim to bring about among well-behaved, hardworking people a measure of equality which shall be substantial, and which shall yet permit to the individual the personal liberty of achievement and reward without which life would not be worth living, without which all progress would stop, and civilization first stagnate and then go backwards. Such a combination cannot be completely realized. It can be realized at all only by the application of the spirit of fraternity, the spirit of brotherhood. This spirit demands that each man shall learn and apply the principle that his liberty must be used not only for his own benefit but for the interest of the community as a whole, while the community in its turn, acting as a whole, shall understand that while it must insist on its own rights as against the individual, it must also scrupulously safeguard these same rights of the individual.

“The only infallible truth of our lives is that everything we love in life will be taken from us.”
