Circular reasoning requires you to use your conclusion inside your reasoning:
http://www.logicalfa...g-the-question/
"An argument is circular if its conclusion is among its premises"
Example:
(1) The Bible affirms that it is inerrant.
(2) Whatever the Bible says is true.
Therefore:
(3) The Bible is inerrant.
(3) = (1), hence circular.
Let's look at this from the catalysts point of view. His premise (it's false if you want as he's not providing proof of it, but that's not up for discussion):
(a) Advanced organics will create synthetics
(
Synthetics will kill all organics (primitive and advanced)
Therefore:
© We will harvest advanced organics and store them in reaper form
We then have:
(a) and (
=> ©
For this to be logically at fault, the first two premises have to be true and his conclusion false as:
V => V = T
F => V = T
F => F = T
V => F = F
Everyone is arguing that the premise (
is false, thus his logical reasoning will always be true because:
V and F => Whatever will always be valid.
Furthermore, his conclusion isn't stated in his premises, so there's no circular reasoning there.
I think you are grossly simplifying the argument and misrepresenting the conclusion.
It could be presented as follows:
a) Advanced Civilisations will develop synthetics

Synthetics will wipe out all organic life
therefore:
We will guide civilisations to exist in a specific pattern of behaviour and advancement then reap them at the point where they will develop synthetics that could wipe out all organic life.
Because that is how their solution works. They shape civilisations until they get advanced enough to make synthetic life, then the Reapers come along to stop the civilisations that they deliberately shaped.
The logic is circular because in order for a or b to be true, the conclusion needs to be in place to make it happen. There is nothing in the logic or information provided that proves that a or b are inevitable except in the case of the Reapers guiding the situation into unfolding in that manner.
Such as in ME1 - the Geth rise up because of Reaper intervention. The Rachni attack because of Reaper intervention. Most of the events that are presented as the reason for the Reapers to come into the galaxy are instigated by Reaper involvement.
