Knowledge, Emotions, and the Human Experience

Descartes

Descartes, a rationalist, believed that true knowledge comes from pure reason. He argued that the senses are misleading and do not provide a true vision of reality, citing illusory illnesses as an example. Geometry, based on pure reasoning, was considered the only reliable source of knowledge. Descartes also defended the existence of innate ideas—knowledge present from birth—such as the existence of God and infinity.

Hume

Hume, an empiricist, believed that experience is the only reliable source of knowledge. He likened the mind to a blank slate filled by lived experiences. Only what could be sensed was considered true and real, leading Hume to critique science, metaphysics, and religion.

Kant

Influenced by Hume, Kant sought to reconcile empiricism and rationalism. He argued that knowledge is not possible without experience, but not all knowledge comes from experience. Kant proposed the existence of a priori knowledge, which he defined as inherent mental structures that shape our understanding of experience. Knowledge begins with experience, but a priori knowledge decodes it.

Damasio

Damasio argues that feelings are primarily physical phenomena. The body reacts to the environment, and the brain interprets these changes as emotions. We feel, then rationalize, and finally decide. Emotions are biologically essential for decision-making.

The traditional view of emotions as external and disruptive is challenged by Damasio. He posits that knowledge involves a physical response (e.g., sweating, increased heart rate) captured by the senses and translated by the peripheral nervous system, producing a feeling that informs our understanding of the environment.

Knowledge as a Survival Mechanism

Knowledge is a survival mechanism with evolutionary roots. It's not simply an accumulation of stored facts, but information processed by the brain based on sensory input. Knowledge is dynamic, not static.
