So I suppose that you need not trouble your head about it, but may just follow the fashions as long as they last.
About this piece of lime, however, Analysis can tell us a great deal.

And we may trust what he says, and believe that he understands what he says.

Think now.

If you took your watch to pieces, you would probably spoil it for ever; you would have perhaps broken, and certainly mislaid, some of the bits; and not even a watchmaker could put it together again.

You would have analysed the watch wrongly.

But if a watchmaker took it to pieces then any other watchmaker could put it together again to go as well as ever, because they both understand the works, how they fit into each other, and what the use and the power of each is.
