سیر حکمت در اروپا، محمدعلی فروغی / جلد ۲ / فصل ۴

This is the opening of a philosophical essay or treatise in Persian that addresses the nature of human knowledge and perception. The text distinguishes between sensory impressions entering the mind from the external world and imaginative constructions created by the mind itself, then begins to introduce an innate category of meanings that the author describes as natural properties of the soul. The work appears to engage with questions about the origin and types of human understanding.
