This book are two lectures given by Searle originally in French at the Sorbonne, Freedom and Neurobiology; and Social Ontology and Political Power. They were really on unrelated subjects.
In Freedom and Neurobiology, Searle explains how freedom of the will can be described by neurobiology. It is part of his project of how to bridge intentional objects, objects with about ness and meaning such as consciousness, intentionally, language, rationality with a world that is made of meaningless elementary particles studied in the sciences. The first interesting observation is about the difference between freedom or volitional state and perceptual states. Perceptual states are passive. You have no choice what to perceive. Volitional state such as your decision to cross the street is active. You decide to cross. The second observation is there is an experiential gap between the antecedent decision to perform an action and the actual performance of the action. Perceptual states don't have such a gap. A third observation is explanation reason to decide in volitional states to perform an action is not a causally sufficient condition to bring about the action such as gravity bringing objects to fall to the ground.
Searle draws an analogy of how to view the solidity of physical objects based on molecular behaviour with how conscious states consist in the states of the neurons in the brain. Solidity is just the molecular states while consciousness is just neuronal states, not over and above them. Searle suggests that in volitional states to act, the neuronal states of consciousness from one state to the next neuronal states are not causally sufficient to move from one to the next. The thought process of reasoning in the neurons does not causally bring one to the other in the volitional process. The consciousness of one state to the other is independent. He sketched out this picture for neurobiology to fill in the details.
In Social Ontology and Poltical Power, he further develops the ideas in his book The Construction of Social Reality to provide an ontology of political power. Searle suggests that humans are different from other social animals capable of living in variousc social modes by creating a political reality using a system of deontic powers, powers from rights, duties, obligations, permissions, authorities, agreed upon by human community that is an institutional reality different from other social reality. This political reality creates a capacity to make humans to perform desire-independent actions, such as you accept to act in certain lawful manner whether you like all the laws or not. Further such political reality or power is often held in place by the political power to use coercive military or police power for compliance. Humans propensity to live in such abstract institutional reality in their own agreement makes them unique
These lectures offers usual Searlian clarity and lucid writing style that make them a pleasure to read and follow. Insights are penetrating as usual.
