Over the past two centuries the character of science has changed markedly and crucially. When humans had relatively small amounts of information and energy available they perforce had no option but to attempt to describe objectively a world which behaved independently of them. The basic practical problem was to discover what the pattern of the world was so as to adapt themselves as best they may to it, a little in anticipation of events, but mostly in reaction to them. It is these circumstances which give most sense to the empiricist paradigm of objective knowledge.
But the more information and energy is available to us, the more we are able to ascend from merely correct description of what is to a grasp of what is possible. Newton's laws don't merely describe the paths of the actual projectiles that have fallen and will fall, they describe the paths of all possible projectiles.
