Bobby Azarian writes: Before Kurt Gödel, logicians and mathematicians believed that all statements about numbers — and reality more generally — were either true or false, and that there must be a rule-based way of determining which category a specific statement belonged to. According to this logic, mathematical proof is the true source of knowledge.… Read More »
Jenny Judge writes: The 55 Bar in Greenwich Village, with its bulging ceiling tiles and strings of fairy lights taped haphazardly to the walls, looks more like the clubhouse of a rural Irish sports team than a New York City jazz venue. Yet some of the musical experiences I’ve had in that dingy basement have… Read More »
David J. Linden writes: When a routine echocardiogram revealed a large mass next to my heart, the radiologist thought it might be a hiatal hernia—a portion of my stomach poking up through my diaphragm to press against the sac containing my heart. “Chug this can of Diet Dr. Pepper and then hop up on the… Read More »
Daniel Ward writes: Suppose that error could be abolished. What would someone who never makes a mistake be like? There are two very different responses to this question. One is to think of a superhuman, god-like being. The poet Alexander Pope’s line – ‘To err is human; to forgive, divine’ – is based on that… Read More »
Robert A Burton writes: In wondering what can be done to steer civilization away from the abyss, I confess to being increasingly puzzled by the central enigma of contemporary cognitive psychology: To what degree are we consciously capable of changing our minds? I don’t mean changing our minds as to who is the best NFL… Read More »
Sally Davies writes: We are shackled to the pangs and shocks of life, wrote Virginia Woolf in The Waves (1931), ‘as bodies to wild horses’. Or are we? Serge Faguet, a Russian-born tech entrepreneur and self-declared ‘extreme biohacker’, believes otherwise. He wants to tame the bucking steed of his own biochemistry via an elixir of… Read More »
By Justin E H Smith Philosophers and cognitive scientists today generally comprehend the domain of reason as a certain power of making inferences, confined to the thoughts and actions of human beings alone. Like echolocation in bats or photosynthesis in plants, reason is an evolved power, but unlike these, the prevailing theory goes, it emerged exactly… Read More »
Our brains make sense of the world by predicting what we will see and then updating these predictions as the situation demands, according to Lars Muckli, professor of neuroscience at the Centre for Cognitive Neuroimaging in Glasgow, Scotland. He says that this predictive processing framework theory is as important to brain science as evolution is… Read More »
Michael Wood writes: Language has many forms of quiet kindness, refusals of stark alternatives. “Never” can mean “not always,” and “impossible” may mean “not now.” Insomnia may mean a shortage of sleep rather than its entire absence, and when Gennady Barabtarlo writes that “Nabokov typically remembered having his dreams at dawn, right before awakening after… Read More »
The Verge reports: One-year-old babies may not be able to speak, but they are able to think logically, according to new research that shows the earliest known foundation of our ability to reason. Legendary psychologist Jean Piaget believed that we didn’t have logical reasoning abilities until we were seven, but scientists scanned the eyes of… Read More »
Frans de Waal asks: are we smart enough to know how smart animals are? Just as attitudes of superiority within segments of human culture are often expressions of ignorance, humans collectively — especially when subject to the dislocating effects of technological dependence — tend to underestimate the levels of awareness and cognitive skills of creatures… Read More »
Laura Ruggles writes: Plants are not simply organic, passive automata. We now know that they can sense and integrate information about dozens of different environmental variables, and that they use this knowledge to guide flexible, adaptive behaviour. For example, plants can recognise whether nearby plants are kin or unrelated, and adjust their foraging strategies accordingly.… Read More »
