As discussed earlier, humanity pursued science as a program for obtaining control over objective reality. While a moral outcome, the principles of science are not moral principles. They are axiomatic statements that define the primitives we can use to change reality. We can use them for good or ill: we can design super-medicines, or cultivate super-diseases. We can create super-materials, or super-weapons.
Science, although manifesting an intention (to control objective reality) and revealing intention (of primitive matter, organisms and societies), does not impose an intention. We do with our knowledge as we will.
On the other end of the problem-solving process, we find engineering. Engineering produces a specific mechanism to solve a specific problem. The artifact, once deployed, manifests the intention of the sponsor that commissioned the design. However, that intention cannot be gleaned from the mechanism by itself.
First, if the mechanism is successful, the problem that motivated its design is solved. Once the problem is removed, how can we know why the mechanism was deployed? Only by removing it. But, once in place, who knows which mechanism came first?
Secondly, the mechanism represents an axiomatic means for creating change. It can, and almost always is, capable of being integrated into some other process. For example, a hammer can be used to drive nails, or to break windows.
Of course, a sophisticated designer might come up with a completely different device for breaking windows: one that doesn't make so much noise as a hammer, for example. But the window-breaker doesn't necessarily have the time and energy for such niceties: consider the parent liberating children trapped in a room by a fire.
