I've been thinking about dualism lately, but one thing that deals a pretty strong blow to this view in my mind is that it implies that the mind can exist apart from physical reality (an immaterial mind or soul, say, that floats out of the body at death).
But isn't a mind, in all of its activity and experience, fully connected to the physical world?
First, any sense perception (which is an integral part of the immediate conscious experience of a mind) is inseparable from some physical organ. Seeing requires an eye, it also requires light to reflect off of physical objects and so on. Thus, sight, sound, smell and all other senses appear incompatible with the experience of some immaterial mind.
Second, even abstract thoughts, intentions, beliefs and so on reduce to some physical structures and events. Thoughts that manifest as language are just examples of sounds and visual symbols that come from the physical world. In other words, take away the senses, and there isn't much consciousness to be had.
Is this kind of objection raised against dualism? Or am I missing something?
