Well, for a start - from a materialist perspective, nothing can determine a cause of a material reaction other than a previous reaction.
Actually, as has been explained,
any system that
exists in time (anything that can do anything that can't be done in zero time, like
choose, contemplate, control, interact, etc.) can
only do things that are either the result previous events or are at at least partly random.
This is a logical limitation, not a 'material' one. It would be good if you could bring yourself to stop lying about this.
So within the endless chains of physically determined reactions going on in your brain, what can possibly incentivise and guide these reactions to perform any form of perceived logical deduction...
Evolved and suitably trained brains. What is the problem? You
never say.
...other than an entity of conscious awareness...
What the fuck is one of those? You need to define what this means
exactly.
...with the power to perceive, control and verify...
All things that are impossible in zero time and hence they are
all subject to the logic above.
Or do you believe that logical deductions can somehow occur naturally without any form of incentive or guidance or verification?
Who do you think is arguing against incentive, guidance, or verification?
If the entity of conscious awareness...
Logically meaningless waffle.
...does play some part in the process of logical deductions then you need to consider how this interaction can take place if conscious awareness emerges from material reactions which have already been determined.
Yet again you have neither produced any argument that indicates there would be any problem with previous reactions nor provided any alternative that would allow for anything else (apart from randomness).
And once again, this
doesn't even look as if it might have been a logical deduction.
What are your premises?
What are the logical steps?
What
exactly is the conclusion?
