The basic difficulties and challenges of Quantum Mind program are analyzed. The conclusion is that the recent form of quantum theory is not enough to overcome the challenges posed by the philosophical problems of quantum physics and quantum mind theories, and the puzzles of quantum biology and quantum neuroscience. Certain anomalies of recent day biology gives hints about how quantum theory should be generalized to serve as an introduction to the summary of the aspects of quantum TGD especially relevant to the notion of Quantum Mind. These include the notions of many-sheeted space-time and field (magnetic) body, zero energy ontology, the identification dark matter as a hierarchy of phases with large value of Planck constant and p-adic physics proposed to define physical correlates for cognition and intentionality.

Especially relevant is the number theoretic generalization of Shannon entropy: this entropy is well defined for rational or even algebraic entanglement probabilities and its minimum as a function of the prime defining p-adic norm appearing in the definition of the entropy is negative. Therefore the notion of negentropic entanglement makes sense in the intersection of real and p-adic worlds and is negative: this motivates the proposal that living matter resides in this intersection.

TGD inspired theory of consciousness is introduced as a generalization of quantum measurement theory. The notions of quantum jump and self defining the generalization of the notion of observer are introduced and it is argued that the notion of self reduces to that for quantum jump. Negentropy Maximization Principle reproduces standard quantum measurement theory for ordinary entanglement but respects negentropic entanglement so that the outcome of state function reduction is not random for negentropic entanglement. The new view about the relationship of experienced time and geometric time combined with zero energy ontology is claimed to solve the basic philosophical difficulties of quantum measurement theory and consciousness theory. The identification of the quantum correlates of sensory qualia and Boolean cognition, emotions, cognition and intentionality and self-referentiality of consciousness is discussed.

About Language, Self Reference and Everything (by Matti Pitkanen):

The ontology of TGD inspired theory of consciousness consist of the trinity formed by objective realities represented by configuration space spinor fields, subjective realities defined by quantum jump sequences between quantum histories (selves), and geometrical objects (res extensa) represented by spacetime surfaces. The infinite-dimensional configuration space of 3-surfaces is believed to be determined completely by the requirement that it allows Kahler geometry free of infinities: infinite- dimensional ontology is fixed by self consistency. Quantum histories (configuration space spinor fields, ’solutions of field equations’) are not only representations for objective realities but identical with them: painting is the landscape so that there is no theory-reality dualism at this level. Quantum histories can be also identified as inhabitants of the Platonic realm of ideas. p-Adic nondetermism and the nondeterminism of the basic variational principle defining configuration space geometry correspond to the nondeterminisms of cognition and language. These nondeterminisms make it possible to represent, not only the quantal aspects of quantum states, but also quantum jumps sequences defining selves as spacetime regions. This explains the self-referentiality of consciousness meaning that it is possible to become conscious of being conscious about something. One ends up to a view about mathematics in which one must distinguish between mathematical ideas at the level of quantum histories and quantum jump sequences (’that which is’), and their cognitive and linguistic representations at spacetime level: the latter ones can never be faithful so that in this sense the map is not the territory.
