 In what follows, we focus on some central issues in Locke’s account of physical objects. (See also the entry  Locke’s philosophy of science,  which pursues a number of topics related to Locke’s account of physical objects that are of considerable importance but largely beyond the scope of this general account of Locke’s philosophy.) These include Locke on knowledge in natural philosophy, the limitations of the corpuscular philosophy and Locke’s relation to Newton.
