 Kant might be referring, on the one hand, to the late 1750s to mid 1760s. A translation of Hume’s Enquiry Concerning Human Understanding (originally published in 1748) appeared in 1755 and was widely read in Germany. Kant had almost certainly read this translation by the mid 1760s, by which time he himself expressed doubts about whether causal connections could be known by reason alone and even suggested that they were knowable only by experience. Or, on the other hand, Kant might be referring to the mid 1770s. After the Inaugural Dissertation appeared in 1770, Kant published nothing more until the first edition of the Critique in 1781. Meanwhile, a German translation of Beattie’s Essay on the Nature and Immutability of Truth (originally published in 1770) appeared in 1772, where, in particular, Beattie quoted extensively from Book 1 of Hume’s Treatise of Human Nature (originally published in 1739). Thus, in the famous “dogmatic slumber” passage, Kant might be referring either to the mid 1760s, when he then had a “remembrance” of reading the translation of Hume’s Enquiry, or to the mid 1770s, when he then had a “remembrance” of reading translations from the  Treatise.[1]
