Un uomo sofferente per strada ha bisogno d'aiuto, gli passiamo accanto senza fermarci perché abbiamo fretta. Ma dopo averlo superato un senso di colpa ci coglie e torniamo indietro per soccorrerlo. Se l'uomo in difficoltà fosse stato un nostro conoscente, avremmo avuto quella esitazione prima di aiutarlo? Siamo tornati indietro spinti da una sincera preoccupazione per l'altro o per ridurre il nostro senso di colpa? Altruisti si nasce o siamo per natura egoisti? Quali sono i vantaggi dell'altruismo per la nostra specie? E cosa accade nel mondo animale? Nel volume si risponde a questi quesiti spiegando come l'aiuto all'altro derivi dalla storia evolutiva del genere umano, ma anche da processi psicologici di natura motivazionale, emotiva e cognitiva.
