Present discussions in philosophy of mind focuson ontological and epistemic characteristics ofmind and on mind-brain relations. In contrast,ontological and epistemic characteristics ofthe brain have rarely been thematized. Rather,philosophy seems to rely upon an implicitdefinition of the brain as "neuronal object''and "object of recognition'': henceontologically and epistemically distinct fromthe mind, characterized as "mental subject'' and"subject of recognition''. This leads to the"brain-paradox''. This ontological and epistemicdissociation between brain and mind can beconsidered central for the problems of mind andmind-brain relations that have yet (...) to beresolved in philosophy. The brain itself hasnot been thematized epistemically andontologically, leading to a "brain problem''.The epistemic and ontological dissociationbetween brain and mind presupposes an"isolated'' picture of the brain, characterizedby context-independence (i.e. "isolation'' frombody and environment). We can describe thisview as an extrinsic relationship betweenbrain, body and environment. However, based onrecent empirical findings about body image andphantom sensations, we can no longer considerthe brain as context-independent or "isolated''from its bodily and environmental context.Instead, the brain must be considered"embedded''. Within the context of 'embeddment',brain and bodily/environmental context seemmutually to determine each other, and hence bereciprocally dependent on each other. We candescribe this as an intrinsic relationshipbetween brain, body and environment.Defining the brain as "embedded'' undermines theepistemic and ontological dissociation betweenbrain and mind and consequently resolves the"brain-paradox''. This resolution sheds novellight on problems of mind and mind-brainrelations by relativizing both. It is thereforeconcluded that philosophy should thematizeontological and epistemic characteristics ofthe brain, thereby taking into account the"brain problem'' and developing a "philosophy ofthe brain''. This approach not only opens a newfield in philosophy but also extends the focusof empirical investigation in the neurosciencesto take into account the intrinsic relationshipbetween brain, body and environment.

The term ``neurophilosophy'' is often used either implicitly or explicitly for characterizing the investigation of philosophical theories in relation to neuroscientific hypotheses. The exact methodological principles and systematic rules for a linkage between philosophical theories and neuroscientific hypothesis, however, remain to be clarified. The present contribution focuses on these principles, as well as on the relation between ontology and epistemology and the characterization of hypothesis in neurophilosophy. Principles of transdisciplinary methodology include the `principle of asymmetry', the `principle of bi-directionality' and (...) the `principle of transdisciplinary circularity'. The `principle of asymmetry' points to an asymmetric relationship between logical and natural conditions. The `principle of bi-directionality' claims for the necessity of bi-directional linkage between natural and logical conditions. The `principle of transdisciplinary circularity' describes systematic rules for mutual comparison and cross-conditional exchange between philosophical theory and neuroscientific hypotheses. The relation between ontology and epistemology no longer is determined by ontological presuppositions i.e. ``ontological primacy''. Instead, there is correspondence between different `epistemological capacities' and different kinds of ontology which consecutively results in ``epistemic primacy'' and ``ontological pluralism''. The present contribution concludes by rejecting some so-called `standard-arguments' including the `argument of circularity', the `argument of categorical fallacy', the `argument of validity' and the `argument of necessity'.
