In this thesis I try to answer the question of what attitude the ancient sceptics had towards the notion of belief. I concern myself exclusively with Pyrrhonic scepticism, as it was described by Sextus Empiricus in his book Pyrrhoniai hypotyposeis. Pyrrhonic scepticism was an epistemological system with ethical ramifications, that questioned most of the conventional wisdom of the time, I begin by evaluating two infleuntial readings, by Michael Frede and Casey Perin. I then go on to make my own assessment. Ultimately, I show why Frede's view is the more plausible; the sceptics allowed themselves to hold beliefs about reality, not just appearance.

This thesis examines and explains how the three Scandinavian populist radical right parties, the Sweden Democrats, the Danish People’s Party and the Progress Party approaches the climate issue in their latest manifesto, and how it has changed over a period of ten years. By means of a content analysis and categorisations of climate scepticism, climate omission and climate measures, this thesis finds explicit evidence of climate scepticism in the Progress Party whereas there is no such evidence for the Sweden Democrats and the Danish People’s Party completely omits the issue. On the other hand, there is evidence of measures to fight climate change in the Progress Party, and the same goes for the Sweden Democrats. However, the only relevant difference when comparing the manifestos over a ten-year period is a decreased usage of statement connected to both climate scepticism and climate action in the Progress Party’s manifestos.
