Dualism is correct. Discuss
Dualism represents a variety of positions that emphasize a fundamental distinction between mental and physical
realms. Substance dualism, championed by Descartes, posits that the mind and body are separate entities, with the
mind being an immaterial, non-physical substance that interacts with the physical body. Conversely, property
dualism asserts that while the mind and body are not distinct substances, certain mental properties or states (e.g.,
qualia) are unique and cannot be reduced to physical properties or states. The most attractive feature of dualism is
its ability to easily accommodate qualia, subjective experience, or as Nagel put it ‘what it is like to be’. However,
several significant objections have been raised, including the problem of other minds and the interaction problem.
This essay will examine both issues but ultimately argue that neither is sufficient to deem dualism incorrect.
The problem of other minds stems from the dualist belief that the mind and mental properties are separate from the
physical world. In this scenario, we can only directly experience our own thoughts and feelings through
introspection. To understand the existence of other people's minds, we must rely on observing their physical actions.
This reliance on observation opens the door to doubt about the existence of others' minds, potentially leading to
solipsism - the idea that only one's own mind is certain to exist. For example, imagine we see a person crying. While
we may assume they are feeling sad or upset, we cannot directly experience their emotions. We are inferring their
emotional state based on their observable physical behaviour - in this case, their tears. This inference leaves room
for doubt, which can fuel scepticism about other minds.
In response to this problem a dualist may employ an argument by analogy drawing comparisons between their own
experiences and the observable behaviours of others. The argument would assert that since there are similarities
between the mental states experienced by the individual and the behaviour exhibited by others, it is reasonable to
infer that other people have minds similar to one's own. For example, when a dualist observes someone else
laughing, they can draw on their personal experiences of laughter and the emotions associated with it, such as
happiness or amusement. They might argue that because their own laughter is a result of their mental state (i.e.,
happiness), it is reasonable to assume that the other person's laughter is also a manifestation of a similar mental
state.
However, this argument can be accused of committing the hasty generalisation fallacy (when someone draws a
conclusion based on insufficient evidence or a limited sample size, resulting in a potentially inaccurate or misleading
conclusion). Hence, just because one's own mental states and experiences are associated with certain observable
behaviours, it is a hasty generalisation to assume that other individuals' observable behaviours are also tied to
similar mental states. It is irresponsible to generalise on such slim evidence.
Still, the dualist may protest that their evidence is far from insufficient. Although they only have direct experience of
their own mind, they have encountered countless instances where their mental states correspond with their
behaviour. These numerous personal examples strengthen their argument, making it more compelling when drawing
parallels between their experiences and the observable actions of others.
While this is a fair point, it is crucial to consider that based on our personal experience not all physical behaviours
are necessarily linked to a mental state. For instance, involuntary actions like reflexes or certain biological processes
occur without any conscious thought. Moreover, the assumption that like effects have like causes may not always
hold true, as different underlying [non-mental] causes could lead to similar observable behaviours. Consequently,
the dualist's argument from analogy is not as robust as it first seems, and suggests we need to consider another
approach.
A better approach is for the dualist to draw on abductive reasoning and argue that the existence of other minds
provides the best explanation for human behaviour by emphasizing the role of mental states as "inner states" that
interact with the environment and drive behaviour. According to this perspective, mental states like beliefs, desires,
emotions, and intentions serve as an intermediary between external stimuli and an individual's actions, allowing for
appropriate and adaptive responses to the environment (e.g. bodily harm triggers the mental state of pain which
