Modeling cognition by structural analysis of representation leads to systematic difficulties which are not resolvable. We analyse the merits and limits of a representation-based methodology to modeling cognition by treating Jackendoff's Consciousness and the Computational Mind as a good case study. We note the effects this choice of methodology has on the view of consciousness he proposes, as well as a more detailed consideration of the computational mind. The fundamental difficulty we identify is the conflict between the desire for modular processors which map directly onto representations and the need for dynamically interacting control. Our analysis of this approach to modeling cognition is primarily directed at separating merits from problems and inconsistencies by a critique internal to this approach; we also step outside the framework to note the issues it ignores.

Are non-human animals conscious? When do babies begin to feel pain? What function is served by consciousness? What evidence could resolve these issues? In The Evolution of Consciousness, psychologist Euan Macphail tackles these questions and more by exploring such topics as: animal cognition; unconscious learning and perception in humans; infantile amnesia; theory of mind in primates; and the nature of pleasure and pain. Experimental results are placed in theoretical context by tracing the development of concepts of consciousness in animals and humans. Written in an accessible style, this book will be of interest to students and professionals in psychology, philosophy, and linguistics, as well as all those interested in the nature of consciousness.

Concerning the question about consciousness, Georges Rey argues that it does not exist from the success of computational theory of human mind. Everything that such a theory requires can be fulfilled by machines which do not have consciousness. So, according to theoretical parsimony, we do not have to attribute consciousness even to human beings. I wish to offer reasons why we should not doubt the existence of consciousness by showing that computational explanations can be explanations of just one part of an aspect of the human mind. Consciousness is also an explanandum rather than an explanans, and the possible reference of “what it is like” expression. Epistemic situation regarding possible accesses to consciousness is also considered.

Perception is sensory awareness. Cognition is reflective awareness. Consciousness is awareness-as-such. In Indian psychology, as represented by Samkhya-Yoga and Advaita Vedanta systems, consciousness and mind are fundamentally different. Reality is the composite of being (sat), knowing (cit) and feeling (ananda). Consciousness is the knowledge side of the universe. It is the ground condition of all awareness. Consciousness is not a part or aspect of the mind. Mind is physical and consciousness is not. Consciousness does not interact with the mind, the brain or any other physical objects or processes. Nor does it have any causative role in mental activity. Hence the existence of consciousness does not interfere or upset the apparently closed physical system. Mind in this view is the interfacing instrumentality that faces consciousness on one side and the brain and the rest of the physical world on the other. Mind is closely connected with the different systems of the brain. In normal perceptions, the mind takes the forms of objects via the channels of the sensory system and the processes in the brain. The forms themselves are non-conscious representations of the world of objects. The mental forms (vrittis) become conscious experiences in the light of the purusha. The vritti in sensory form is perception and with the reflection of the purusha it becomes cognition. All conscious perceptions are therefore cognitions.
