Piet Rofessor is a PhD student at Leiden Univeristy whose main area of interest can be found in political philosophy. Most notably, Piet is interested in different conceptions of liberty, republicanism and French political theorist Benjamin Constant. Apart from political philosophy, Piet is also interest in metaethics. Debates in metaethics are fruitful and related to a variety of other academic disciplines. The genereal consensus in the scientific community seems that with the help of neurobiology, and other emperical studies, we seem to discover more and more about our ethical intuitions and therefore about the status of morality. However, it is Piet's contention that these questions remain fundamentally philosophical in nature and unanswerable using only science. Part of his dissertation is commited to defending this position.

Doing so allows Piet to combine a certain metaethical position (a view largely coinciding with Brink's Cornell Realism) with a certain normative position. Specifically, this will be a defence of Constant's conception of liberty. Furthermore, Piet will hold that Benjamin Constant's philosophy fits neatly in the current republican tradition (as found in works of Skinner and Pettit) and that it is possible to view Constant as a predecessor to- or possibly as the originator of this modern republicanism. This section of the dissertation will consist of two parts: firstly, Piet will make a plea as to why Constant's conception of liberty is republican and secondly, why this is the only defensible conception of liberty. There is also a (to a certain extent latent) interest in existentialism, specifically in Sartre and Camus.
