Chapter 1: The Foundations of Self-Knowledge

The esteemed French philosopher René Descartes famously established his epistemological theory with the assertion "cogito, ergo sum," which translates to "I think, therefore I am." Descartes suggested that, while he could conceive of existing without his physical body, the notion of existing without his mind was unfathomable. Hence, the mere act of thinking served as proof of his existence.

Despite its prominence, Descartes' philosophy faced criticism even in his time. The philosopher and Catholic priest Pierre Gassendi contended that Descartes had merely shown that thinking occurred, not that this thinking originated from a singular entity. Gassendi argued that inferring the presence of a thinker from a sequence of thoughts was a logical fallacy.

More recently, British philosopher P.F. Strawson presented a more profound critique of Descartes’ epistemology in his work "Individuals." He challenged the notion that our self-concept is the cornerstone of all knowledge, including the understanding of other minds. In fact, Strawson posited that our comprehension of others precedes our understanding of ourselves.

Strawson’s reasoning is as follows: if one lacked any notion of other minds, would they need to articulate feelings of pain or fear? His assertion is clear: one would simply experience these sensations and respond accordingly. The act of assigning mental states to oneself arises only after developing the habit of attributing such states to others.

The reasoning behind cultivating this habit is compelling. Other minds are significant components of our surroundings. It is advantageous to envision the thoughts and intentions of those we interact with, whether they are competitors, allies, or potential threats.

Thus, Strawson argues that the notion of a person or agent is both logically and biologically prior to the concept of self. He elaborates that if our understanding of others' minds comes before our self-awareness, then our conception of a person—encompassing both physical and mental aspects—predates our notion of a disembodied self. This assertion is grounded in the fact that our only insight into others’ mental states derives from observing their physical actions.

The construct of a disembodied self relies on the belief in private subjective experiences, which, in turn, hinges on the concept of self—an idea that is inherently dependent on understanding others. Therefore, Descartes' belief that the certainty of his mind's existence was paramount was fundamentally misguided.

Recent empirical findings lend credence to Strawson's argument. Research by Yale's Laurie Santos indicates that rhesus macaques prefer to pilfer fruit when they perceive that observers are unaware of their actions. This suggests that these primates recognize that others may lack knowledge of their intentions (e.g., "I’m taking your fruit").

However, there is no solid evidence to suggest that macaques possess self-awareness. Testing for self-recognition in animals is notoriously challenging. A common method involves anesthetizing an animal, marking it, and then presenting a mirror. If the animal touches the mark on its own body, researchers infer that it recognizes the reflection as itself.

Few species pass this test, but among those that do not, many still demonstrate the capacity to infer the mental states of other individuals.

Consequently, Strawson’s argument, supported by Santos’ findings, reinforces the intuitive belief that, in terms of survival and reproduction, responding appropriately to social and ecological signals is more crucial than engaging in introspection. Our awareness of others precedes, and only through that awareness do we come to know ourselves.

The first video titled "How We See Ourselves Through The Eyes Of Others" explores how self-perception is influenced by social interactions and the perspectives of others.

The second video, "David Myers - How Do We Know Ourselves? | STM Podcast #152," delves into the complexities of self-identity and how it is shaped by external influences.
