An adjective used to describe an explanation based on a purpose, goal, or intended outcome.
In science, particularly in evolutionary biology, we speak of teleological language when a process is described as if it were directed toward a future result.
Example:
“An organism develops a trait in order to adapt better.”
This wording can suggest that evolution is pursuing a goal. A more precise explanation would be that, within a population, certain variations may provide reproductive advantages and, through natural selection, become more frequent over successive generations.
The distinction is also important in artificial intelligence and complex systems. When we say that a system “wants to persist”, “tries to optimise itself”, or “seeks to survive”, we may be attributing an intention that is not required to explain its behaviour.
In short: a teleological explanation describes a process in terms of its apparent purpose or outcome, whereas a causal explanation aims to describe the mechanisms that produce that outcome.
