Nature equips us with feelings to determine value
Choice and avoidance is the mechanism that evolved to help increase the survival of animals. As Dr. Morten L. Kringelbach, a professor of neuroscience at Aarhus University, Denmark and University of Oxford, UK, wrote in a 2016 paper1: “The selection of hedonic reactions has required the evolution of mammalian brains to dedicate millions of developing neurons into mesocorticolimbic patterns of reward circuitry (Haber and Knutson, 2010). Such neural investment was subject to the same selection pressures that shaped evolution of any other function. Hedonic circuitry was therefore unlikely to have been shaped into its present form, or to have persisted throughout evolution, unless objective affective reactions actually conveyed significant consequences in terms of benefits for survival and fitness (Anderson and Adolphs, 2014; Damasio, 2010; Kringelbach and Berridge, 2010; LeDoux, 2012; Panksepp, 2011).”1
