Between perception and action

What mediates the fleeting moment between seeing an apple and reaching out to grasp it? This fundamental question, at the very heart of understanding the mind, reveals a profound and often overlooked mechanism. It is argued that the vast majority of our actions, from the simplest to the seemingly complex, are not born from intricate webs of beliefs and desires, but rather spring directly from a more primitive, yet incredibly sophisticated, form of perception.

Imagine tying your shoelaces, or picking up a cup. These everyday acts, often performed without conscious deliberation, are guided by what are called "pragmatic representations." These are not abstract thoughts or reasoned intentions, but immediate perceptual states that actively represent the properties of objects relevant for interaction. When you see the apple, your visual system isn't just registering its redness or roundness; it's simultaneously registering its size relative to your hand, its distance, its graspability - all the "action-properties" crucial for a successful reach. These are the cognitive components that immediately precede and enable our actions.

This perspective suggests a "deintellectualization" of action, proposing that our minds, much like those of infants and non-human animals, are primarily geared towards successful interaction with the world through direct perceptual guidance. The traditional view, which places sophisticated propositional attitudes like beliefs and desires as the default drivers of intentional action, is often inadequate. Instead, many of our actions are rooted in these more basic, action-oriented perceptual states.

Pragmatic representations are genuine perceptual states, arising directly from sensory input. They are not merely an optional addition to perception, but are argued to be necessary antecedents for most "basic" actions - those fundamental movements not composed of other actions. For instance, the buzz of a mosquito isn't just heard; it's pragmatically represented in a way that facilitates the swatting motion, demonstrating their multimodal nature, extending beyond just vision.

The framework then expands beyond immediate perception to consider how our minds bridge the gap even when direct sensory input is absent. This introduces the concept of "pragmatic mental imagery." This quasi-perceptual form of mental imagery, differing from direct perception primarily in the determinacy of its content, allows us to attribute action-relevant properties even when an object is not physically present. It offers compelling explanations for phenomena such as pretend actions or the semi-automatic, often irrational, activities that shape our daily lives.

Further still, the understanding of action-oriented perception extends to how we comprehend the movements and intentions of others through "vicarious perception." Here, one perceives properties pertaining to the possible actions of another agent. This notion offers a powerful lens through which to re-examine long-standing questions about how infants and animals develop an understanding of other minds, suggesting that such complex social cognition might be rooted in these shared, sensorimotor capacities.

Embracing this understanding of pragmatic representations fundamentally reshapes debates in both the philosophy of perception and the philosophy of action. It challenges the dominance of belief-desire psychology and offers a compelling alternative that grounds sophisticated cognitive abilities, such as action-planning and interpersonal understanding, in the immediate, action-guiding functions of perception. It provides a robust, interdisciplinary framework for exploring the intricate dance between what we see, what we imagine, and what we ultimately do in the world.
