Avicenna on abstraction

Abstract
The theory of abstraction is one of the most puzzling parts of
Avicenna's philosophy. What Avicenna says in many passages about the
human intellect's capacity to derive universal knowledge from sense-data
seems to plainly contradict passages in the same works about the emanation
of knowledge from the active intellect, a separately existing substance.
When he maintains that "considering the particulars [stored in
imagination] disposes the soul for something abstracted to flow upon it
from the active intellect", 1 he appears to combine two incompatible concepts
in one doctrine: either the intelligible forms emanate from above or
they are abstracted from the data collected by the senses, but not both.
