David Hume, a luminary of 18th-century Scottish intellectual circles, left an indelible imprint on philosophy and theology. His profound speculations arguably held the most significant influence of his era, rivalled only by Adam Smith in a certain sphere. Humes impact was not immediately recognized, with time needed to dispel misconceptions and reveal his true intellectual stature. Now, over a century later, we can appreciate his work and its repercussions more objectively. Hume is undeniably a grand and autonomous thinker, and this text examines his philosophical approach as an attempt to understand human knowledge and morality, without attributing it to a rational human nature.
