BERKELEY: The Principles of Human Knowledge

The Anglo-Irish philosopher George Berkeley once said “Esse est percipi,” which means “to be is to be perceived.” According to Berkeley, only minds and ideas exist; matter does not exist. He discusses this theory, which will later be referred to as subjective idealism, in his treatise titled, The Principles of Human Knowledge. In this video, we will explore Berkeley’s radical ontology, which, if accepted, resolves many philosophical paradoxes that have haunted mankind from time immemorial.

ST. THOMAS AQUINAS: Summa Theologica [Part I, QQ 75-76, 78-79]

75 – In Question 75, Aquinas argues that the human soul is incorporeal because corporeal bodies are not the principle of life, else all bodies would be alive.

PLOTINUS: Sixth Ennead

Plotinus is an ancient Greek philosopher who lived from 205-270 BC. He belongs to the philosophical school of Neoplatonism, which expanded upon the metaphysical concepts of Plato. In the Sixth Ennead, Plotinus discourses on the nature of Being, and the nature of the One in particular. The One is Plato’s Form of the Good. It is that from which all existence is derived. Plotinus writes that defining the One is impossible. We must intuit its existence. In order to accomplish this union with the One, we must lead an ascetic life, in which we take little heed of the body and we focus our attention on metaphysical truths. Plotinus’ thoughts have had a significant role in the formation of Christian thought, which has dominated the West for several millennia. Continue reading PLOTINUS: Sixth Ennead
