G. A. Cohen in “More on Exploitation and the Labour Theory of Value” defends the thesis that the Marxist charge of exploitation against the capitalist cannot be supported by way of the labour theory of value. He suggests an alternative, non-labour-theoretic argument for this charge which depends on premises he takes to be more obvious than the labour theory of value. Cohen claims that his argument is the only way a Marxist couldjustify attributions of “exploitation” to the capitalist, if any such justification is possible. In this paper, I will argue that, given Cohen's objections to the labour-theoretic argument, his “Plain Argument” itself retains too great a similarity to that argument. A new interpretation of the basis of the charge of exploitation is offered which requires neither the labour theory nor that which is dubious in Cohen's formulation.

A well-known ``overdetermination''argument aims to show that the possibility of mental causes of physical events in a causally closed physical world and the possibility of causally relevant mental properties are both problematic. In the first part of this paper, I extend an identity reply that has been given to the first problem to a property-instance account of causal relata. In the second, I argue that mental types are composed of physical types and, as a consequence, both mental and physical types may be causally relevant with respect to the same physical effect, contrary to the overdetermination argument. In further sections, I argue that mental types have causal powers, consider some objections and reject an alternative version of part-whole physicalism. Throughout I assume that causal relata are tropes and property types are classes of tropes.
