The Nature of Artifacts and Technical Functions
Quick fact
The same object can have different technical functions depending on the user's intention—a screwdriver can be a pry bar, a paperweight, or even a weapon.
Why this is interesting
Think of a stone: in a river, it's just a rock. But put it on a shelf to hold a door, and suddenly it has a technical function. How does a physical object become a tool?

Understanding The Nature of Artifacts and Technical Functions
An artifact is a human-made object, but what makes it a specific artifact (like a 'cup' or a 'chair') isn't just its shape—it's the intention behind its creation and use. Technical functions are not intrinsic; they are assigned. For example, a wooden stick can be a walking aid if someone decides to use it that way. The function is a relation between the object's physical properties and a user's goal. This means the function is not in the object alone, but in the interaction.
A deeper explanation
Philosophers like Beth Preston distinguish between 'proper functions'—those intended by the designer and part of the artifact's standard use—and 'system functions'—those arising from current use in a particular context. A chair's proper function is to sit on, but if you stand on it to change a lightbulb, it's serving a system function. The technical function of an artifact is thus a normative concept: it tells us what the artifact is 'supposed' to do, but this can change over time or with different users. This matters because it affects how we attribute responsibility (who is at fault if a tool fails?), how we design for specific purposes, and how we understand the evolving relationship between humans and technology. Importantly, the artifact’s material constraints enable and limit possible functions, so a plastic fork cannot become a knife, but it can be a makeshift screwdriver. Thus, technical functions are the result of a dynamic interplay between design intention, material affordance, and user practice.
