THE TRUTH OF DESTINY
As a result of experiments he performed in 1973, Professor Benjamin Libet, a neurophysiologist at the University of California, revealed that all our decisions and choices are set out beforehand, and that consciousness only comes into play half a second after everything has been determined.44 This is interpreted by other neurophysiologists as meaning that we actually live in the past and that our consciousness is like a monitor which shows us everything half a second later.
Therefore, none of the experiences we perceive are in real time, but are delayed by up to half a second from the real events themselves. Libet carried out his research by making use of the fact that brain surgery can be performed without the use of narcosis, in other words while the subject is fully conscious. Libet stimulated the brains of his subjects with small electrical currents, and when they experienced a perception that their hands had been touched the subjects said that they had felt that "touch" almost half a second before. As a result of his measurements, Libet arrived at the following conclusion: All perceptions are normally transmitted to the brain. As these are subconsciously evaluated and interpreted, the ego is unaware of anything. The information that appears before our minds, in other words that we can be aware of, is transmitted to the cortex, the seat of consciousness, after a certain delay.45
The conclusion from this may be summarised as follows: The decision to move a muscle takes place before that decision reaches the consciousness. There is always a delay between a neurological or perceptual process and our becoming aware of the thought, feeling, perception or movement it represents. To put it another way, we can only be aware of a decision after that decision has been taken.
In Professor Libet's experiments, this delay varies between 350 and 500 milliseconds, although the conclusion that emerges is in no way dependent upon those figures. Because, according to Libet, whatever the length of that delay-it makes no difference whether it is great or small, whether it lasts an hour or a microsecond-our material life is always in the past. This demonstrates that every thought, emotion, perception or movement happens before reaching our consciousness, and that proves that the future is entirely outside our control.46
In other experiments, Professor Libet left the choice of when the subjects would move their fingers up to them. The brains of the subjects were monitored at the moment their fingers moved, and it was observed that the relevant brain cells went into action before the subjects actually took the decision. To put it another way, the command "do!" reaches the individual, and the brain is readied to perform the action; the individual only becomes aware of this half a second later. He or she does not take a decision to act and then performs that action, but rather performs an action predetermined for him or her. Yet, the brain makes an adjustment, removing any recognition that the individual is actually living in the past. For that reason, at the moment we refer to as "now," we are actually living something determined in the past. As already discussed, these studies manifest the fact that everything happens by the will of Allah, as revealed in Surat al-Insan 30.
