Quick Definition
Nous is a Greek term often translated as "mind," "intellect," or "reason," but its meaning is richer and more nuanced than these simple translations suggest. It signifies the capacity for intellectual thought and intuitive understanding, a power that allows humans to comprehend the essential nature of reality.
In ancient Greek philosophy, particularly in the works of Plato and Aristotle, nous plays a central role in their metaphysical and epistemological theories. It is viewed as the highest part of the soul, capable of grasping the Forms or eternal truths that exist beyond the physical world.
Plato associates nous with the realm of Forms, suggesting that it is through nous that humans can access and contemplate these perfect and unchanging realities. This faculty allows for a kind of direct apprehension of truth, unmediated by the senses.
Aristotle distinguishes between active and passive nous. Passive nous is the receptive faculty that receives impressions from the senses, while active nous is the agent intellect that illuminates these impressions and abstracts universal concepts from them.
The active nous, according to Aristotle, is divine and immortal, representing the part of the human soul that is most closely connected to the divine intellect. This connection allows humans to attain knowledge of the highest truths.
The concept of nous has been influential throughout the history of Western philosophy, impacting various schools of thought, including Neoplatonism and medieval philosophy. Thinkers like Plotinus and Augustine incorporated nous into their systems, further developing its significance.
In Neoplatonism, nous is seen as the second emanation from the One, the ultimate source of all being. It is the realm of intellect and thought, containing all the Forms or Ideas that are the archetypes of the sensible world.
The understanding of nous has implications for ethics as well. By cultivating our intellectual faculties and striving to understand the truth, we can achieve a higher level of moral and spiritual development, aligning ourselves with the divine order of the cosmos.
