Insistence on Impermanence Is not Nihilism

To serve their purpose, names and terms must of necessity be fixed and definite like all other units of measurement. But their use is-up to a point-so satisfactory that man is always in danger of confusing his measures with the world so measured, of identifying money with wealth, fixed convention with fluid reality. But to the degree that he identifies himself and his life with these rigid and hollow frames of definition, he condemn himself to the perpetual frustration of one trying to catch ...

 Abstraction is a Necessity for Communication

The English words "man," "fish," "star," "Hower," ·run," "grow," all denote classes of objects or events which may be recognized as members of their class by very simple attributes, abstracted from the total complexity of the things themselves. Abstraction is thus almost a necessity for communication, since it enables us to represent our experiences with simple and rapidly made "grasps" of the mind. When we say that we can think only of one thing at a time, this is like saying that the Paci...

 History in Games

Of what use is the past to a gamer? Peter Lunenfeld: “For the most part, its blood, mischief and role playing that gamers revel in. They live in an alternative universe, a solipsistic one scripted by designers whose frame of reference extends no further back than Pong, Pac-Man and Dungeons and Dragons. The visual and storyline tropes that most of us bring with us as cultural baggage are… all but forgotten ancestral memories, thrown off, on purpose, too cumbersome to be of any use.” In t...

 A Lack of Uncertainty Impacts Learning in Adults

Healthy aging can lead to impairments in learning that affect many laboratory and real-life tasks. These tasks often involve the acquisition of dynamic contingencies, which requires adjusting the rate of learning to environmental statistics. For example, learning rate should increase when expectations are uncertain (uncertainty), outcomes are surprising (surprise) or contingencies are more likely to change (hazard rate). In this study, we combine computational modelling with an age-comparativ...

 Q

The hypothesis of {108} abstraction says that every living creature is characterized by a number Q which is a measure of the complexity of the creature. To measure Q, we do not need to know anything about the internal structure of the creature. Q can be measured by observing from the outside the behavior of the creature and its interaction with its environment. Q is simply the quantity of entropy produced by the creature's metabolism during the time it takes to perform an elementary respons...

 800 Lifespans Bridge 50,000 Years

Eight hundred life spans can bridge more than 50,000 years. But of these 800 people, 650 spent then lives in caves or worse; only the last 70 had any truly effective means of communicating with one another, only the last 6 ever saw a printed word or had any real means of measuring heat or cold, only the last 4 could measure time with any precision; only the last 2 used an electric motor; and the vast majority of the items that make up our material world were developed within the lifespan of t...

 Defining "Uncertainty"

‘Uncertainty’ is a complex and multifaceted property, sometimes originating in a lack of information, and at other times from quite fundamental disagreements about what is known or even knowable (Moss and Schneider, 2000). Furthermore, scientists often disagree about the best or most appropriate way to characterize these uncertainties: some can be quantified easily while others cannot. Moreover, appropriate characterization is dependent on the intended use of the information and the parti...
