 Recipe for Modernism

Here is the recipe: Look at a complex and confusing reality, such as the social dynamics of an old city Fail to understand all the subtleties of how the complex reality works Attribute that failure to the irrationality of what you are looking at, rather than your own limitations Come up with an idealized blank-slate vision of what that reality ought to look like Argue that the relative simplicity and platonic orderliness of the vision represents rationality Use authoritarian power to imp...

 Three Brain Pathways to Reading

The frontal reading system has been implicated in phonological processing and semantic processing (word analysis). This is also where Broca’s area is found. Broca’s area is involved in language processing, speech production, and comprehension. Neuron activation is increased in this area when words are spoken (Devlin, Matthews, & Rushworth, 2003). The ventral posterior processing system (located in the occipital and temporal lobes) is most associated with orthographic processing (visu...

If you earned a dollar for every second in your life, you would be a billionaire. However, a second can feel like a minute in front of an audience, and a quiet weekend can disap...

 The Brain Creates Models of the World

We make models in science, but we also make them in everyday life. Model-dependent realism applies not only to scientific models but also to the conscious and subconscious mental models we all create in order to interpret and understand the everyday world. There is no way to remove the observer—us—from our perception of the world, which is created through our sensory processing and through the way we think and reason. Our perception—and hence the observations upon which our theories are...
