"if we could sufficiently understand the order of the universe, we should find that it exceeds all the desires of the wisest men, and that it is impossible to make it better than it is,not only as a whole and in general but also for ourselves in particular, if we are attached, as we ought to be, to the Author of all, not only as to the architect and efficient cause of our being, but as to our master and to the final cause, which ought to be the whole aim of our will, and which can alone make our happiness."

...from Leibniz Monadology 90

I found that the phrase "all is well and wisely put" is in a beautiful poem "Fable" by Ralph Waldo Emerson.
