According to legend, inscribed on walls of the temple on the sacred site of Delphi in Ancient Greece were two premier injunctions: NOTHING IN EXCESS, and KNOW THYSELF. This course will be an examination of the latter injunction in an effort to discover what self-knowledge is, why it might be valuable, and what, if any, limitations it might face. What is missing from a person lacking in self-knowledge that makes her less wise, virtuous, or competent in certain areas than others who have this capacity, and what if anything might she do to fill that gap? Historical sources as well as recent research in philosophy, experimental social psychology, and neuroscience will inform our investigation, in the course of which we will become students of our own dreams, and cultivate some meditative practices. Learning Outcomes: Learners will gain familiarity with prominent themes from Western, classical Chinese, and Buddhist approaches to our knowledge of ourselves. In the course of doing so, they will gain an appreciation of the relation of self-knowledge to wisdom, of the value of intellectual humility, as well as of methods of learning about oneself that do not depend on introspection. Learners will also become familiar with contemporary research in experimental social psychology, philosophy, and neuroscience into the emotions, the unconscious, the role of affect in decision making, and self-deception. They will also gain an appreciation of a challenge to the assumption of a coherent, unified self that derives from the Buddhist tradition. --- This course was created by a partnership between The University of Edinburgh and Humility & Conviction and Public Life Project, an engaged research project based at the University of Connecticut and funded by a generous grant from the John Templeton Foundation.

Descartes' Essence
Are you dreaming right now? How do you know you're not? Rene Descartes set himself a pretty titanic task: to doubt absolutely everything he cannot be certain of - even that the world exists! - and then try to see if we can rebuild our knowledge of ourselves and the world only from what we can be really certain of. In the process, he formulated some provocative thoughts on the radical separation of the mind from the body.

So, if you're starting out with a question,
what kinds of things are there?
What kinds of things exist?
Then, there are two primary answers to that question.
One of which is known as monism,
the answer namely is one kind of thing.
The other which is known as dualism,
the answer there are two kinds of things.
Standardly, monism could take either one or two forms,
the most popular being,
what's known as materialistic monism.
That is that everything that exists is matter or some force or property of matter.
And if you're a materialist monist you'll say,
even people are purely physical things,
even their thoughts are purely physical processes.
You could also be a monist by holding that
everything in a sense is mental but the only things that
exist are in some sense ideas that's if we
associate with the philosopher George Berkeley,
not something that we'll be trying to defend here or explain here,
but there is a version of monist that says everything
is as it were ideal as opposed to material.
Whereas on the other side is the dualistic position
which says that there are two kinds of
things and a purely physical description of
the universe will never be a complete description.
If you're a dualist you're going have to worry about a couple of different questions.
As I adumbrated before,
common sense seems to show that as an everyday occurrence,
mental events can bring about physical changes and likewise in the other direction.
But if you're a dualist, it's not quite clear how that interface is going to go.
Descartes did a fair bit of vivisection,
that is operating on animals,
not all of whom were dead at the time.
He always did a lot of dissection of human corpses and he found inside
human brains what we now know to be a genuine part of
the brain that's now referred to as the pineal gland.
And he thought that maybe the pineal gland is the locus,
the place at which mind and body interact.
But claiming that mind and body interact at the pineal gland or at any other place,
just raises all those old questions over again.
How do those things interact?
According to the principle of the causal closure of the physical,
every physical event that has a cause,
so we are going to have to assume that every physical event does have a cause.
But every physical event that does have a cause has a purely physical cause.
That seems to be a pretty deep presupposition of modern physics for example,
but if you're a dualist, you're going to have to deny that.
Because if you're a dualist, you're going to have to say
that there are mental events that are
not identical with any physical events that bring about physical changes.
And that would seem to be a violation of
the principle of the causal closure of the physical.
So, one consequence that should make
a dualist scratch your head and wonder what's going on,
is the fact that the dualist seems to fly in the face of both the common sense,
fact the mind-body seem to interact,
and the fact that seems like it's
a deep part of physics that the physical world is causally closed.
They seem to have to run against those two,
it seems facts and if you're not
going to run against them you'll have some explaining to do.
Likewise, it seems like if you're a dualist
a mystery arises as to how it is we could know about somebody else's mind.
If dualism is right then we know about our own minds in an introspective way that
seems to produce a high degree of confidence
but how do I know about what's happening in somebody else's mind?
Common sense suggests that on an everyday basis,
especially for those people that I have lots of interaction with,
I can often know what's going on inside of their mind,
I can tell by this person's furrowed brow that she's irritated.
I can tell by that person's continuing to fidget
with their hair that they're distracted or that they're angry.
But if you're a dualist in the tradition of Descartes,
that's going to be a mystery and in particular,
there's never going to be any way of finding out for sure what's going on in
somebody's mind because even if you were to
open up their cranium and look inside their brain,
you would never be able to get any conclusive evidence
of what's happening with them mentally.
Whereas, if you're a materialist you at least have hope that
that sort of thing could be established beyond a shadow of a doubt.
So, those are not absolute reputations of dualism,
they're things rather that raised questions for dualistic position that
the defender of that position is going to have to say more about to either explain them,
explain them away etc.
Final point I want to make about Descartes and his project for now is the
following: whereas with Socrates and his interlocutors,
we found that learning about oneself,
knowing about oneself had to do not just with
knowledge but to some extent also brought in the notion of wisdom.
That is to say, being wise when we try to figure out what it means,
what the Delphic Oracle meant in saying that no one is wiser than Socrates,
involved not just knowledge about oneself but knowledge of one's limitations,
one's ignorance and thereby why what we
thought was what made that valuable and made Socrates
to have a bit of an edge over many of his fellow Athenians was
that by virtue of being aware of his limitations,
he was more likely to be able to act wisely not act foolishly,
not hastily interpret things that the Oracle said
and thereby go into battle and have his empire destroyed for example.
Whereas Descartes says not very much about wisdom,
at least in the writings that we've looked at,
but mostly about knowledge.
Where and we often notice that one could
have a lot of knowledge without necessarily being wise.
So, there's not an obvious connection between
Descartes notion of self knowledge and Socrates.
Socrates gives us a notion that perhaps in some ways is
more satisfying because it has to do with the wisdom not just knowledge.
At the same time however,
Descartes gives us a method that he hopes will be rigorous,
as a way of helping us move out of our knowledge of ourselves to knowledge of
the external world in ways could bound up with
the rigorization of modern mathematics and modern science.
And also as a powerful argument for that helps us answer
the question what is the relationship between the mind and the body?
Either we're going to accept that with its consequent puzzles or we'll have to find
a way in which Descartes might have been mistaken and that's
a set of questions of what we'll move onto in our next lecture.
