For Anarchy, State, and Utopia (1974) Nozick received a National Book Award in category Philosophy and Religion. There, Nozick argues that only a minimal state "limited to the narrow functions of protection against force, theft, fraud, enforcement of contracts, and so on" could be justified without violating people's rights. For Nozick, a distribution of goods is just if brought about by free exchange among consenting adults from a just starting position, even if large inequalities subsequently emerge from the process. Nozick appealed to the Kantian idea that people should be treated as ends (what he termed 'separateness of persons'), not merely as a means to some other end.
the growth, stability, and expansion of powerful states governed by representative democracy was in part a creation of the credit market, bondholders, and international finance. That’s not a world in which democratic decision makers ever had unconstrained sovereign decision-making authority over public finance, even in the powerful core states of the international system. It also means that the representative state emerged out of a kind of market competition for creditworthy providers of government. The representation of those who would have to be taxed in the future to repay the debt was taken as much more credible than a king’s prediction that his son would probably find the money somewhere.
A public address is embedded inside the output “script” so that it can only be spent using the private key corresponding to that public address. If we consider this output to be a database row, what we have is a database with per-row permissions which are based on public key cryptography. Furthermore, every transaction presents a publicly auditable proof that its creator(s) had the right to delete/modify its prior rows. This (I believe) is a genuine novelty in database technology.
In artificial intelligence, an intelligent agent (IA) is an autonomous entity which observes through sensors and acts upon an environment using actuators (i.e. it is an agent) and directs its activity towards achieving goals (i.e. it is "rational", as defined in economics). Intelligent agents may also learn or use knowledge to achieve their goals. They may be very simple or very complex: a reflex machine such as a thermostat is an intelligent agent.
