Where does aquinas’ cosmological argument appear
First three of his three ways for proving the existence of god in summa theologica
What’s way 1 of aquinas 5 ways
Motion and change
What’s way 2 of aquinas 5 ways
Causation
Whats way 3 if aquinas 5 ways

What did aquinas observe to reach his argument
The cosmos
What is the cosmological argument
That everything we observe is contingent because they all rely on something else to exist because they are moved ,changed and caused therefore there must be is something that has necessary existence for evrything else to exist
What’s premise one of the argument of contingency and necessity
P1 Everything can exist or not-exist: that is, everything in the natural world is contingent.
What’s premise 2 of the argument of contingency and necessity
P2 If everything is contingent, then at some time there was nothing, because there must have
been a time when nothing had begun to exist.
What’s premise 3 of the argument of contingency and necessity
P3 If there was once nothing, then nothing could have come from nothing.
What’s conclusion 1 of the argument of contingency and necessity
C1 Therefore, something must exist necessarily, otherwise nothing would now exist, which is
obviously false.
What’s premise 4 of the argument of contingency and necessity
P4 Everything necessary must either be caused or uncaused.
What’s premise 5 of the argument of contingency and necessity
P5 But the series of necessary beings cannot be infinite, or there would be no explanation of that
series.
What’s conclusion 2 of the argument of contingency and necessity
C2 Therefore, there must be some uncaused being which exists of its own necessity.

What’s a fallacy
A failure in reasoning which makes an argument invalid
What’s the fallacy of composition
fallacy
of inferring that something is true of the whole from the fact that it is true of part of the whole,
or of every part of the whole.
What’s an example of the fallacy of composition
I. Hydrogen is not wet; oxygen is not wet.
II. Therefore water (H20) is not wet.
At what ‘way’ does Russell aim his criticism at
Way 2 the argument from causation
Does fallacy of composition apply to every argument
No , for example if you say the walls are build of bricks so the wall is brick . This is taking a part and making it a whole but it’s valid .
What is Russell’s criticism
That way 2 commits a fallacy of composition
Who says way 3 is not fallacious
Bruce Reichenbach suggests that Way 3 resembles the brick argument so it’s not committing fallacy of composition.
