For instance, the people who routinely get themselves screened for being a carrier for Tay-Sachs disease are a demographic who have an extremely strong historical reason to be worried about Nazi-style dysgenics, and yet, eugenics is exactly what they are doing whenever a couple of them, on learning that they are both carriers, decide to refrain from having children together, or break off their relationship and seek other, non-carrier partners. The Nazis thought they were practising eugenics. From their point of view, they were improving the gene pool: People will disagree on which types of eugenics are good and which are bad.

Mind—body problem The mind—body problem concerns the explanation of the relationship that exists between mindsor mental processesand bodily states or processes.

Our perceptual experiences depend on stimuli that arrive at our various sensory organs from the external world, and these stimuli cause changes in our mental states, ultimately causing us to feel a sensation, which may be pleasant or unpleasant.

Someone's desire for a slice of pizza, for example, will tend to cause that person to move his or her body in a specific manner and in a specific direction to obtain what he or she wants. The question, then, is how it can be possible for conscious experiences to arise out of a lump of gray matter endowed with nothing but electrochemical properties.

It begins with the claim that mental phenomena are, in some respects, non- physical. In Western Philosophythe earliest discussions of dualist ideas are in the writings of Plato who maintained that humans' "intelligence" a faculty of the mind or soul could not be identified with, or explained in terms of, their physical body.

He was therefore the first to formulate the mind—body problem in the form in which it still exists today. If asked what the mind is, the average person would usually respond by identifying it with their selftheir personality, their soulor some other such entity.

They would almost certainly deny that the mind simply is the brain, or vice versa, finding the idea that there is just one ontological entity at play to be too mechanistic, or simply unintelligible. So, for example, one can reasonably ask what a burnt finger feels like, or what a blue sky looks like, or what nice music sounds like to a person.

But it is meaningless, or at least odd, to ask what a surge in the uptake of glutamate in the dorsolateral portion of the prefrontal cortex feels like. Philosophers of mind call the subjective aspects of mental events " qualia " or "raw feels".

There are qualia involved in these mental events that seem particularly difficult to reduce to anything physical. David Chalmers explains this argument by stating that we could conceivably know all the objective information about something, such as the brain states and wavelengths of light involved with seeing the color red, but still not know something fundamental about the situation — what it is like to see the color red.

Dualism must therefore explain how consciousness affects physical reality. One possible explanation is that of a miracle, proposed by Arnold Geulincx and Nicolas Malebranchewhere all mind—body interactions require the direct intervention of God. Another possible argument that has been proposed by C.

Lewis [33] is the Argument from Reason: Knowledge, however, is apprehended by reasoning from ground to consequent. Therefore, if monism is correct, there would be no way of knowing this—or anything else—we could not even suppose it, except by a fluke.

The zombie argument is based on a thought experiment proposed by Todd Moody, and developed by David Chalmers in his book The Conscious Mind. The basic idea is that one can imagine one's body, and therefore conceive the existence of one's body, without any conscious states being associated with this body.

Chalmers' argument is that it seems possible that such a being could exist because all that is needed is that all and only the things that the physical sciences describe about a zombie must be true of it. Since none of the concepts involved in these sciences make reference to consciousness or other mental phenomena, and any physical entity can be by definition described scientifically via physicsthe move from conceivability to possibility is not such a large one.

It has been argued under physicalism that one must either believe that anyone including oneself might be a zombie, or that no one can be a zombie—following from the assertion that one's own conviction about being or not being a zombie is a product of the physical world and is therefore no different from anyone else's.

This argument has been expressed by Dennett who argues that "Zombies think they are conscious, think they have qualia, think they suffer pains—they are just 'wrong' according to this lamentable tradition in ways that neither they nor we could ever discover!

Seth has a clear and distinct idea of his mind as a thinking thing that has no spatial extension i. He also has a clear and distinct idea of his body as something that is spatially extended, subject to quantification and not able to think.

It follows that mind and body are not identical because they have radically different properties. A child touches a hot stove physical event which causes pain mental event and makes her yell physical eventthis in turn provokes a sense of fear and protectiveness in the caregiver mental eventand so on.

Descartes' argument crucially depends on the premise that what Seth believes to be "clear and distinct" ideas in his mind are necessarily true.

Many contemporary philosophers doubt this. Freud claimed that a psychologically-trained observer can understand a person's unconscious motivations better than the person himself does.The Biology of Mind Neuron Communication Neuron is a nerve cell, basic building block our nerve system Neurons consists in: Dendrites: neurons bushy branches and it listens.
