Defending Plato's Renunciation of Art

November 12th, 2012 in Article, Arts + Media, Opinion, Pop Culture 0 comments

This is in reference to a 2011 lecture entitled “Plato’s Philosophy of Art”, given by Dr. James Grant of the University of London, Birkbeck. An audio recording of the lecture can be found at the bottom.

Today, Plato is probably known best for his work Republic, an outline of a highly idealistic and just city-state. Many remember bits and pieces from their Intro to Philosophy classes, but a criticism that is generally brushed over in discussion of the Republic is Plato’s flat-out renunciation of art. A prerequisite in understanding Plato’s position is realizing the role that art, and specifically poetry, played in Greek culture.

Poetry in the time of Plato played a similar role to the Bible in early American culture. Sections were recited at schools, in homes, and children were expected to memorize various passages for later recitation. Much like the Bible, these poems formed early moral backbones in young Greeks and were very much responsible for the development of certain cultural norms. It wasn’t so much a problem for Plato that art had such a grip on the cultural norms and moral fibers of a society, but rather that the artists themselves had no understanding of what they were representing, and thus inspired corrupt and destructive morals. In the eyes of Plato, the artist or poet was typically not the ideal moral character in any society, and thus should not have been in charge of dictating moral grounds or developing cultural norms. A second complaint Plato had about the role of the artist was that even if they were generally a moral and civilized human being, they were falsely representing reality through their art, something which Plato very much opposed to and which undermined a central theory in Platonism.

Spatial Cognition in Philosophy and Neuroscience

February 29th, 2012 in Article 2 comments

In this post, I attempt to present two major metaphysical accounts of space by Kant and Leibniz, then present some recent findings from cognitive neuroscience about the neural basis of spatial cognition in an attempt to understand more about the nature of space and the possible connection of philosophical theories to empirical observations.

Immanuel Kant’s account of space in his Prolegomena serves as a cornerstone for his thought and comes about in a discussion of the transcendental principles of mathematics that precedes remarks on the possibility of natural science and metaphysics. Kant begins his inquiry concerning the possibility of ‘pure’ mathematics with an appeal to the nature of mathematical knowledge, asserting that it rests upon no empirical basis, and thus is a purely synthetic product of pure reason (§6). He also argues that mathematical knowledge (pure mathematics) has the unique feature of first exhibiting its concepts in a priori intuition which in turn makes judgments in mathematics ‘intuitive’ (§7.281). For Kant, intuition is prior to our sensibility and the activity of reason since the former does not grasp ‘things in themselves,’ but rather only the things that can be perceived by the senses. Thus, what we can perceive is based on the form of our a priori intuition (§9). As such, we are only able to intuit and perceive things in the world within the framework naturally provided by the capabilities and character (literally the under–standing) of our understanding. Kant then takes our intuitions of space (and time) as concepts integral to pure mathematics and as necessary components of our intuition (§10.91). More

Are We Born With Knowledge?

February 22nd, 2012 in Uncategorized 2 comments

One thing I have always struggled with in reading philosophy is the doctrine of Innatism, which holds that the human mind is born with ideas or knowledge. This belief, put forth most notably by Plato as his Theory of Forms and later by Descartes in his Meditations, is currently gaining neuroscientific evidence that could validate the belief that we are born with innate knowledge of our world.

Do You See What I See?

October 18th, 2011 in Article, Opinion 0 comments

Philosophy of Mind came into its most compelling forms during the age of modern philosophy beginning with René Descartes. Perhaps infamously, Descartes claimed that mind and body are two distinct substances – philosophical jargon for what exists without the aid of any other thing. For Descartes, the world was clearly and distinctly physical in one sense and entirely mental in another. This seems perplexing, and Descartes did concede that the mind and body were closely intertwined and appeared to act with respect to one another, but his arguments clearly press that they are not causally connected in any way. These notions of dualism seem nearly preposterous with the advent of modern science, but were nonetheless important in developing our thought about the mind in the modern era.

Dualism gave rise to other interesting, yet now strongly refuted movements. One of these was idealism, or the doctrine argued famously by George Berkeley that states that all that exists are either ‘ideas’ or minds that perceive them. In this sense, an idea is defined as that which is perceived, inclusive of information imprinted on the senses, passions and operations of the mind, and conceptions formed by imagination and memory. Importantly, Berkeley argues that these ideas exist ‘in the mind’ exclusively: that is, they are purely mental and all things are simply combinations and aggregations of ideas. These immaterial ‘ideas’ then, are the only objects of human knowledge under idealism, and this theory denies the existence of physical objects entirely! The notion seems preposterous, but there is a very interesting argument found within idealism that can throw our conception of perception for quite the proverbial loop. More

Most would agree that the most important of our basic senses is sight. Without it, many basic forms of communication fall apart, the vibrance of the world around us dulls, and our understanding and ability to sense the complexity of the physical world diminishes. Without the ability to see, it would logically be impossible to portray our surroundings artistically in a coherent and visually realistic manner…

…wait…what? More

The Hard Problem of Consciousness

July 26th, 2011 in Uncategorized 13 comments

You’re lying on a sandy beach on a hot sunny afternoon, enjoying a few hours of much needed laziness. As you open your eyes and confront the vastness of the ocean in front of you, light of 600nm wavelength hits your retina, kindling an impossibly long cascade of events in your brain: a molecule called retinal changes shape, neurons fire action potentials down the optic nerve, arrive at the lateral geniculate nucleus deep in the brain causing more action potentials in primary visual cortex in the back of your head, and so on ad infinitum. At some point, the mechanical wonder of 100 billion neurons working together produces something special: your experience of the color blue. What’s special is not that you can discriminate that color from others; nor that you are aware of it and paying attention to it. It is not notable that you can tell us about it, or assign a name to it. It’s that you have a subjective, qualitative experience of the color; there is something it is like to experience the color blue. Some philosophers call these experiences qualia – meaning “what kind” – but it is not important what kind of experience you are having, just that you are having one at all. Modern science hypothesizes that subjective experience is a product of the brain, but has no explanation for it. More

Mind the Gap

October 29th, 2010 in Uncategorized 4 comments

The discoveries of modern neuroscience have certainly heightened our understanding of the brain and its functions, and have begun to provide us with a physical groundwork for the complicated problem of effectively investigating the mind. While it is certainly beneficial to establish physical principles that underly cognitive function of the brain, how does this effect the larger endeavor of understanding the mind? Neuroscientists such as Rebecca Saxe of MIT are converging on things like the nuroanatomical basis of moral judgment and just scraping the surface of what can bridge the gap between what physically “is” and what metaphysically “ought” to be. In her experiments, Saxe proposes that she has pinpointed the right temporoparietal junction (RTPJ) as a brain center for making moral judgments and has conducted experiments with magnetic brain stimulation that can effectively change the moral judgments of her subjects. Please see her TED talk here for a full explanation of her study.

Crossing the gap at the wrong time can lead to dire consequences.

Crossing the gap at the wrong time can be devastating.

In the 1700s, David Hume proposed what has now become known widely as the Is-Ought Problem. He calls for caution in making statements about morality or what “ought” to be based on extrapolations of what “is” and that what ought to be does not necessarily follow from what is. The problem aptly applies to neuroscientists like Saxe whose research make strong suggestions about the neural basis of existence and attempts to bridge the is-ought gap. All of this research is establishing a large library of what “is” concerning the brain, but it also suggests that metaphysical concepts such as morality and meta-ethics can be reduced to neurological connections and connectivity. Hume stresses that while what is and what ought to be are important revelations in and of themselves, what ought to be need not follow from what is. Neuroscience must understand this separation as its advances begin to encroach on many of philosophy’s already well-established concepts.


Brain activity is only one component of our consciousness.

What I’m saying here is that modern neuroscience must use caution in making conclusions about human nature. Empirical evidence can certainly be used to help understand more abstract ideas, but the evidence and the ideas must remain seperate with respect to causality. Making discoveries about brain function and the empirical science behind things like emotion or judgment is a valiant and respectable scientific investigation. However, this pursuit must be kept separate and distinct from the pursuit of understanding how we ought to be or act. Our moral thought is something more abstract and multidimensional than connections between neurons and sequential acton potentials. While investigation of the science of the mind is important, it should not seek to explain our existence nor try to answer philosophy’s greatest problems with calculations and empirical data.
