Wahrheit und Gewissheit

Truth is agreement between thought and reality and thus expresses a relation between the contents of our consciousness and the object of our knowledge. Certainty, however, is not a relationship but a capacity, a quality, a state of the knowing subject. (…) Certainty exists when the spirit finds complete rest in its object of knowledge.
