Hume is widely regarded as the third and most radical
of the British empiricists, after John Locke and George Berkeley.
Like Locke and Berkeley, Hume argued that all knowledge results
from our experiences and is not received from God or innate to our
minds. This kind of empiricism led to today’s “scientific method,”
which holds that knowledge should be based on observations rather
than intuition or faith. Radical empiricism went further, arguing
that our knowledge is nothing more than the sum of our experiences.
Unlike Locke and Berkeley, Hume removed God from the equation completely
and argued forcefully against the possibility of his existence as
his contemporaries envisioned it.
