Telegraph. She was twice awarded the Medical Journalists’
Association prize
for outstanding contribution to medical journalism.
Rita was on the panel of The
Great Debate: Evolution, Human Nature and Autonomy in March 2001,

Debate: Whatever Happened to the
Subject? in March
2004 and the Battle of
Ideas Great Debate
The Rise and Rise of Evolutionary Psychology with Caspar
Hewett
in October 2005.
Rita says
I believe we are determined because humans are part of the natural universe and (as far as we know) the natural universe is entirely governed by the laws of cause and effect. I see no reason why we should regard ourselves as somehow outside that framework — nor have I heard a convincing argument as to how we COULD be outside it.
I therefore believe freewill is an illusion. The reason it is so utterly convincing is that the illusion — like the illusion that the objects around us are solid, or have some integral color — is deeply wired into the brain as a set of mechanisms which automatically create the sense of self/ subjectivity and agency that makes it feel as though we decide what our acts will be rather than merely respond to stimuli. There is, I believe, evidence to show that this is the case: e.g. Libet’s famous experiment showing that the brain begins an action before consciousness of it emerges. Neuroscience is also unravelling the mechanism of self and agency and these are now charted well enough for them to be copied in AI systems. These “self-sensing” robots will, I believe, develop the same sense of agency and subjectivity that Kenan Malik claims is unique to mankind and distinguishes us from machines.
Today a brain scan reveals our thoughts, moods, and memories as clearly
as an X-ray reveals our bones. We can actually observe a person’s brain
registering a joke or experiencing a painful memory. Drawing on the
latest imaging technology and the expertise of distinguished
scientists, Rita explores the geography of the human brain. Her
writing is clear, accessible, witty, and
Mapping the Mind’s 150
illustrations — most in color — present an illustrated guide
to that
wondrous, coconut-sized, wrinkled gray mass we carry inside our heads.
Mapping the Mind charts the way human behavior and culture
have been
molded by the landscape of the brain. Rita shows how our
personalities reflect the biological mechanisms underlying thought and
emotion and how behavioral eccentricities may be traced to
abnormalities in an individual brain. Obsessions and compulsions seem
to be caused by a stuck neural switch in a region that monitors the
environment for danger. Addictions stem from dysfunction in the brain’s
reward system. Even the sense of religious experience has been linked
to activity in a certain brain region. The differences between men and
women’s brains, the question of a “gay brain”, and conditions such as
dyslexia, autism, and mania are also explored.
Looking inside the brain, writes Rita, we see that actions follow
from our perceptions, which are due to brain activity dictated by a
neuronal structure formed from the interplay between our genes and the
environment. Without sidestepping the question of free will, Rita
suggests that future generations will use our increasing knowledge of
the brain to “enhance those mental qualities that give sweetness and
meaning to our lives, and to eradicate those that are destructive.”
In
Exploring Consciousness,
Rita ponders the nature, origins, and purpose of consciousness
in this fascinating inquiry into the toughest problem facing modern
science and philosophy. Building on the foundation of her bestselling
book Mapping the Mind, she considers whether consciousness is merely an
illusion, a by-product of our brain’s workings, some as yet
inexplicable feature or property of the material universe or — as
the
latest physics may suggest — the very fundament of reality.
Little, she
discovers, is as it first seems.
She draws from a solid body of knowledge — empirical findings
and
theoretical hypotheses — about consciousness, much of it derived
from
recent discoveries about the brain. Her lively, accessible narrative
ranges widely over new ways of thinking about the subject and what
direction new research is taking. Leading scholars from a range of
perspectives provide topical essays that complement her account.
The book also discusses how traditional approaches —
philosophical,
scientific, and experiential — might be brought together to create
a
more complete understanding of consciousness.
What is known about the workings of the human brain has increased
immeasurably in recent times. Drawing on the latest discoveries,
Mapping the Memory: Understanding Your Brain to Improve Your
Memory offers readers a unique scientific approach to
improve their memory.
Presenting a wealth of information in a highly accessible format,
Mapping the Memory explains the different types of memory:
episodic
(what happened), semantic (facts), procedural (how to do things), and
working (everyday routines).
It then details which parts
of the brain
govern memory and how memory loss can be controlled. Self-assessment
questionnaires, memory exercises, case studies, therapies, tips, and
tricks are all included to help readers reach a higher level of
understanding about memory and how they can improve the working of
their own brain function in this area.
Multiplicity: The New Science of Personality, Identity, and the
Self presents an entirely new view of our selves. Instead of
seeing each person as a single personality, Rita argues that we all
consist of multiple characters, each one with its own viewpoint,
emotions and ambitions. The mother who feeds breakfast to her children,
for example, has quite different concerns and opinions from the woman
taking part in a boardroom discussion two hours later, and from the
woman she will be with her husband that night. Yet all three may share
the same body, and none is any more “authentic” than
another.
Personality changes in a person are conventionally frowned upon, but
Rita shows that in today’s world our ability to switch from one
personality to another according to what is demanded of us is a huge
strength, providing one’s personalities work together as a team rather
than against each other. In addition to its groundbreaking scientific
thesis,
Multiplicity contains extensive exercises designed to help
readers achieve this harmony.
