The emergence of a unified cognitive moment relies on the coordination of scattered mosaics of functionally specialized brain regions. Here we review the mechanisms of large-scale integration that counterbalance the distributed anatomical and functional organization of brain activity to enable the emergence of coherent behaviour and cognition. Although the mechanisms involved in large-scale integration are still largely unknown, we argue that the most plausible candidate is the formation of dynamic links mediated by synchrony over multiple frequency bands.

The interdependence of word and idea shows clearly that languages are not actually means of representing a truth already known, but rather of discovering the previously unknown. Their diversity is not one of sounds and signs, but a diversity of world perspectives [Weltansichten]. ... The sum of the knowable, as the field to be tilled by the human mind, lies among all languages, independent of them, in the middle. Man cannot approach this purely objective realm other than through his cognitive and sensory powers, that is, in a subjective manner.

As with emotionally drawn-out religious initiations, neurobiological studies of stress disorders indicate that subjects become intensely absorbed by sensory displays. The mystical experiences of schizophrenics and temporal lobe epileptics, which may be at the extreme end of the "normal" distribution of religious experience, also exhibit intense sensory activity. These may help to inspire new religions. There is no evidence, however, that more "routine" religious experiences that commit the bulk of humanity to the supernatural have any characteristic pattern of brain activity.

Haavelmo was the first to recognize the capacity of economic models to guide policies. This paper describes some of the barriers that Haavelmo's ideas have had (and still have) to overcome, and lays out a logical framework that has evolved from Haavelmo's insight and matured into a coherent and comprehensive account of the relationships between theory, data and policy questions. The mathematical tools that emerge from this framework now enable investigators to answer complex policy and counterfactual questions using simple routines, some by mere inspection of the model's structure.

The unconscious is the larger circle which includes within itself the smaller circle of the conscious; everything conscious has its preliminary step in the unconscious, whereas the unconscious may stop with this step and still claim full value as a psychic activity. Properly speaking, the unconscious is the real psychic; its inner nature is just as unknown to us as the reality of the external world, and it is just as imperfectly reported to us through the data of consciousness as is the external world through the indications of our sensory organs.

The passions are a kind of thirst, inexorable and intense, for certain feelings or felt states. To find or invent 'objects' (which are, more strictly speaking, relational structures) whose felt quality satisfies the passions,- that for me is the activity of the artist, an activity which does not cease even in sleep. No wonder the artist is constantly placing and displacing, relating and rupturing relations; his task is to find a complex of qualities whose feeling is just right – veering toward the unknown and chaos, yet ordered and related in order to be apprehended.
