1 The human mind is the very idea or knowledge of the 2 human body (II. xiii.), which (II. ix.) is in God, in so far as 3 he is regarded as affected by another idea of a particular thing 4 actually existing: or, inasmuch as (Post. iv.) the human body 5 stands in need of very many bodies whereby it is, as it were, 6 continually regenerated; and the order and connection of ideas 7 is the same as the order and connection of causes (II. vii.); 8 this idea will therefore be in God, in so far as he is regarded 9 as affected by the ideas of very many particular things. Thus 10 God has the idea of the human body, or knows the human body, in 11 so far as he is affected by very many other ideas, and not in so 12 far as he constitutes the nature of the human mind; that is (by 13 II. xi. Coroll.), the human mind does not know the human body. 14 But the ideas of the modifications of body are in God, in so far 15 as he constitutes the nature of the human mind, or the human 16 mind perceives those modifications (II. xii.), and consequently 17 (II. xvi.) the human body itself, and as actually existing; 18 therefore the mind perceives thus far only the human body. 19 Q.E.D. 20 21
