While Frege believed that logic might prescribe laws about how people should think, logic is not the science of how people do think.

As Garavaso and Vassallo rightly emphasize, Frege takes grasping a thought ffrege be only necessary but not sufficient for knowledgesince knowledge requires both holding the thought to be true ‘judging’ it so, as Frege uses the term and also having sufficient justification for doing so, e. The final chapter focuses on the function of language in enabling human thinking, by making thoughts and truths accessible to human consciousness Chapter 5. In this short book, Pieranna Garavaso and Nicla Vassallo aim to re-focus discussions of Frege toward two neglected aspects of his gedwnke Basil Blackwell NagelE.

The Metaphysics of Gottlob Frege. While the truth of an identity statement involves only the references of the component expressions, the informativity of such statements involves additionally the way in which those references are determined, i. Kneale, William and Martha Kneale.

He was forced to quickly prepare an appendix in response. This omission also means that Garavaso and Vassallo do not attempt any comparison with a Kantian classification of the various types of thinking that humans are capable of, though this comparison would have been useful in helping to sharpen the precise import of their positive account of Frege on thinking Chapter 3.

In Frege’s own usage, by contrast, ‘purely logical’ thinking seems to require this further characteristic — roughly:
