in all particular thoughts, which latter are conceived thereby.
Thought, therefore, is one of the infinite attributes of God,
which express God's eternal and infinite essence (Pt. i., Def.
vi.). In other words, God is a thinking thing. Q.E.D.

Note.--This proposition is also evident from the fact, that we
are able to conceive an infinite thinking being. For, in
proportion as a thinking being is conceived as thinking more
thoughts, so is it conceived as containing more reality or
perfection. Therefore a being, which can think an infinite
number of things in an infinite number of ways, is, necessarily,
in respect of thinking, infinite. As, therefore, from the
consideration of thought alone, we conceive an infinite being,
thought is necessarily (Pt. i., Deff. iv. and vi.) one of the
infinite attributes of God, as we were desirous of showing.

PROP. II. Extension is an attribute of God, or God is an
extended thing.

Proof.--The proof of this proposition is similar to that of
the last.

PROP. III. In God there is necessarily the idea not only of his
essence, but also of all things which necessarily follow from his
essence.

Proof.--God (by the first Prop. of this Part) can think an
infinite number of things in infinite ways, or (what is the same
thing, by Prop. xvi., Part i.) can form the idea of his essence,
and of all things which necessarily follow therefrom. Now all
that is in the power of God necessarily is (Pt. i., Prop. xxxv.).
Therefore, such an idea as we are considering necessarily is, and
in God alone. Q.E.D. (Part i., Prop. xv.)

Note.--The multitude understand by the power of God the free
will of God, and the right over all things that exist, which
latter are accordingly generally considered as contingent. For
it is said that God has the power to destroy all things, and to
reduce them to nothing. Further, the power of God is very often
likened to the power of kings. But this doctrine we have refuted
(Pt. i., Prop. xxxii., Corolls. i. and ii.), and we have shown
(Part i., Prop. xvi.) that God acts by the same necessity, as
that by which he understands himself; in other words, as it
follows from the necessity of the divine nature (as all admit),
that God understands himself, so also does it follow by the same
necessity, that God performs infinite acts in infinite ways. We
further showed (Part i., Prop. xxxiv.), that God's power is
identical with God's essence in action; therefore it is as
