Epistemology largely came to the fore in philosophy during the early modern period, which historians of philosophy traditionally divide up into a dispute between empiricists (including John Locke, David Hume, and George Berkeley) and rationalists (including René Descartes, Baruch Spinoza, and Gottfried Leibniz). The debate between them has often been framed using the question of whether knowledge comes primarily from sensory experience (empiricism), or whether a significant portion of our knowledge is derived entirely from our faculty of reason (rationalism). According to some scholars, this dispute was resolved in the late 18th century by Immanuel Kant, whose transcendental idealism famously made room for the view that "though all our knowledge begins with experience, it by no means follows that all arises out of experience". While the 19th century saw a decline in interest in epistemological issues, it came back to the forefront with the Vienna Circle and the development of analytic philosophy.
