Ernest Sosa has made and continues to make major contributions to a wide variety of topics in epistemology. In this paper I discuss some of his core ideas about the nature of knowledge and scepticism. I start with a discussion of the safety account of knowledge – a view he has championed and further developed over the years. I continue with some questions concerning the role of the concept of an epistemic virtue for our understanding of knowledge. Safety and virtue hang very closely together for Sosa. All this easily leads to some thoughts on epistemic scepticism and on Sosa's stance on this.

More than 300 years ago, William Molyneux raised an important and puzzling question which still creates a lot of controversy. What is known as “Molyneux’s question“ was made famous by John Locke’s quote of Molyneux in the second edition of the Essay Concerning Human Understanding: “Suppose a Man born blind, and now adult, and taught by his touch to distinguish between a Cube, and a Sphere of the same metal, and nighly of the same bigness, so as to tell, when he felt one and t’other, which is the Cube, which the Sphere. Suppose then the Cube and Sphere placed on a Table, and the Blind Man to be made to see. Quaere, Whether by his sight, before he touch’d them, he could now distinguish, and tell, which is the Globe, which the Cube.“ I argue for a positive answer to the question.

The possibility of knowledge attributions across contexts (where attributor and subject find themselves in different epistemic contexts) can create serious problems for certain views of knowledge. Amongst such views is subject—sensitive invariantism—the view that knowledge is determined not only by epistemic factors (belief, truth, evidence, etc.) but also by non—epistemic factors (practical interests, etc.). I argue that subject—sensitive invariantism either runs into a contradiction or has to make very implausible assumptions. The problem has been very much neglected but is so serious that one should look for alternative accounts of knowledge.

Kant's political philosophy in general is characterized by two aspects which sometimes compete with each other and sometimes supplement each other: an individualist element on the one hand and a social or "communitarian" element on the other hand. This paper deals with Kant's theory of private property. It attempts to show something that is usually overlooked in the secondary literature: that Kant has two, not just one argument for property. One is based on his theory of freedom and expresses the individualist aspect of his thinking. The other argument is based on Kant's principle of right and expresses the social aspect of his political thought. Despite some problems with his arguments the complexity of Kant's theory remains impressive.
