No. Not even close.
Take a look at, say, a piece of cutlery. You could learn everything about how it was produced, how it works, etc., but that wouldn't answer why it was made. One person looking at it might think it was made to stab people with. And it could be. Someone else might think, of all things, to keep a few papers from blowing away. Still another person might think it an entertaining way of passing the time by throwing it at a target.
Of course, actually knowing why it was made, we can say it's supposed to be used in the preparation of food. The hows give no indication and does not determine the why.
