I'm afraid your assertions are incorrect. Whilst there may be little empirical evidence of subconsciousness and unconsiousness in the Freudian definitions, there is substantial evidence for subconscious processes in the cognitive sense. No one fully controls their memory, emotion or awareness-it is not possible.
Very simple computerised experiments provide evidence for what is termed implicit memory-literally memory without consciousness for the event. Words can be flashed up on a computer screen for such a short period of time that viewers claim to have seen nothing at all-e.g they have not consciously viewed the stimuli. However, when later asked to identify these words from a list, people choose the words they were shown, but didn't 'see', at a remarkable level of accuracy, even when they literally feel they have only guessed which words were flashed upon the screen.
An alternative experiment is using a subliminal prime, for example flashing one word on the screen very quickly followed by a second word for a longer period of time (the first word is too quick to become conscious but the second is consciously processed by the participants). Participants have to press keys to say whether the second word is an actual word or not. They are much quicker at doing this and more accurate if the first, subliminal word is semantically related to the second. For example, they would be quicker at recognising that 'nurse' is a word if the subliminal flash was 'doctor'. Non-words could be something like 'nurge'. Thus 'doctor' has primed 'nurse' and increased the recognition speed of that word even though 'doctor' was not consciously seen. I'm sure you'll appreciate then that not only does this show a lack of control for memory, but also for awareness-the participants cannot choose to be consciously aware of the prime, as it is too quick yet they also cannot choose to not have a memory for it, as an implicit memory develops outwith their control.
Impicit memory and awareness can also be seen in clinical cases. Patients with anterograde amnesia (an inability to create new memories) can learn something new even without a conscious memory of the learning process. For example, they become significantly quicker at putting a jigsaw puzzle together on repeated attempts, even though they have no memory of ever seeing the jigsaw puzzle before. Their increased speed and accuracy at doing the puzzle is a sign of learning with no memory or awareness for learning!
These are behavioural phenomena that psychology has uncovered and studied, not biology.
Also, if we are in complete control of our cognitive faculties tell me this, could you listen to a thousand people talking all at once for an hour then repeat to me verbatim exactly what each had said? You would be able to do this if you had complete control of your memory and awareness. Could you forget your own name for a day, then remind yourself to remember what it is again? Could you make yourself cry despairingly then laugh whole heartedly on demand and truly feel those emotions within the space of one minute?
Your statement is paradoxical, you cannot state that there is an abscence of free will but also purport that we are in total control of our brain, memory, awareness and emotion.
I would welcome any counter arguments you can supply! :-)
