1 Imagination or conception is the idea, by which the 2 mind regards a thing as present (II. xvii. note), but which 3 indicates the disposition of the mind rather than the nature of 4 the external thing (II. xvi. Coroll. ii.). An emotion is 5 therefore a conception, in so far as it indicates the disposition 6 of the body. But a conception (by II. xvii.) is stronger, so 7 long as we conceive nothing which excludes the present existence 8 of the external object; wherefore an emotion is also stronger or 9 more intense, when we conceive the cause to be with us at the 10 present time, than when we do not conceive the cause to be with 11 us.
