Abstract

ACCORDING TO HUSSERL, THE REVOLUTION brought about by the new mathematical science of the seventeenth century was primarily an ontological one: a shift in the conception of the real. That Husserl opposes the new Galilean-Cartesian ontology is clear. This much is evident from the potent rhetoric of the Crisis declaiming Galileo as an "entdeckender und verdeckender Genius", forgetful of the lifeworld, failing to grasp what the mathematical-empirical method he brought to such a degree of perfection actually achieves. Indeed, even without the ringing Crisis passages, one could already expect that Husserl, the phenomenologist, would oppose the Platonizing scientific realism of a Galileo or a Descartes. However, Husserl's critique of Galileo poses many puzzling questions, questions which are not directly addressed in the Crisis, and which can be answered only in terms of the broader position outlined by Husserl elsewhere. To whit: what is the more precise content of Husserl's objections against Galileo, and how are these justified? Further, if scientific realism is to be rejected on phenomenological grounds, does this imply that a phenomenological approach is necessarily instrumentalist? Finally, what solution does Husserl's thought offer to the realism/instrumentalism debate?
