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'.

Quine famously holds that "philosophy is continuous with natural science". In order to find out what exactly the point of this claim is, I take up one of his preferred phrases and trace it through his writings, i.e., the phrase "Science itself teaches that …". Unlike Wittgenstein, Quine did not take much interest in determining what might be distinctive of philosophical investigations, or of the philosophical part of scientific investigations. I find this indifference regrettable, and I take a fresh look (...) at Quine's metaphilosophy, trying to defuse his avowed naturalism by illustrating how little influence his naturalistic rhetoric has on the way he actually does philosophy.
