Proximate causation

Philosophy
Philosophy is the study of general and fundamental problems, such as those connected with existence, knowledge, values, reason, mind, and language. Philosophy is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational...

 a proximate cause is an event which is closest to, or immediately responsible for causing, some observed result. This exists in contrast to a higher-level ultimate cause (or distal cause) which is usually thought of as the "real" reason something occurred.
  • Example: Why did the ship sink?
    • Proximate cause: Because it was holed beneath the waterline, water entered the hull and the ship became denser than the water which supported it, so it couldn't stay afloat.
    • Ultimate cause: Because the ship hit a rock which tore open the hole in the ship's hull.


In most situations, an ultimate cause may itself be a proximate cause for a further ultimate cause. Hence we can continue the above example as follows:
  • Example: Why did the ship hit the rock?
    • Proximate cause: Because the ship failed to change course to avoid it.
    • Ultimate cause: Because the ship was under autopilot and the autopilot's data was inaccurate.


Separating proximate from ultimate causation frequently leads to better understandings of the events and systems concerned.

In Biology

  • Ultimate causation answers questions of why an animal behaves the way it does. Ultimate causes take into account environmental factors that contribute to why an animal is able to survive and reproduce. They tie directly into the concepts of Darwinism and natural selection. Ultimate causation has an end goal in forwarding genes and ensuring survival.
Example: A female songbird is attracted to male songbirds' songs. These songs also warn other males to stay away from the singer’s territory. Male songbirds that sang in the spring were naturally selected for; they attracted more mates, reproduced more, and passed their genes on.
  • Proximate causation answers questions of how biological traits operate in an animal. Whereas ultimate causation has long-term implications, proximate causes have more immediate effects. These causes explain why certain animals have certain appendages, for example, but are independent of the evolutionary discussion.
Example: Increased light during springtime triggered the male songbirds brain to produce a sex hormone. These hormones drove the birds to sing.


According to E. Mayr, “There is always a proximate set of causes and an ultimate set of causes; both have to be explained and interpreted for a complete understanding of the given phenomenon.” To understand both the biological and evolutionary importance of behaviors, it’s essential to determine both the proximate and ultimate causes of behaviors. Greenberg states that: "Ultimate and proximate causes are not incompatible explanations; they are simply on different scales.” In the songbird example, we can see the survival aspect of the behavior (ultimate) and the biological aspect through which the behavior occurs (proximate).

Ultimate and proximate causation tie into functionalism, which is “an attempt to explain behavior in terms of what it accomplishes for the behaving individuals.” The psychological perspective of functionalism looks at the traits of mammalian ancestors and attempts to explain how those traits helped each member to pass their genes on.

Criticisms of the terms proximate and ultimate have arisen in recent years. B. Thierry argues that the two terms are too uniformitarian, and fail to take into account genetic drift and environmental inheritance. He states that several biologists have dubbed the terms obsolete, because they focus too heavily on external factors. Now, rather, these terms are utilized regularly by behavioral psychologists and ecologists. He states: “Today many of us are keen on integrating mechanisms, development, adaptation and historical contingency in a unified theory of evolution. To this aim, however, trying to reconcile proximate and ultimate causation is counter-productive, for this very formulation perpetuates their separation.”

Most sociologists recognize that proximal causality is the first type of power humans experience; however, while factors such as family relationships may initially be meaningful, they are not as permanent, underlying, or determining as other factors such as institutions and social networks (Naiman 2008: 5).

relative to each other, it is the social structure and institutions in which these exist that are the ultimate cause of behaviour. A human biography can only be told in relation to the social structure, yet it also must be told in relation to unique individual experiences in order to reveal a complete picture (Mills 1959).
