Mankind has essential needs: food, water, clothing, shelter, and reproduction. Around the world, and throughout history, groups develop standard methods for obtaining and sustaining these needs. We have legal, social, religious and governmental norms within each culture. Normality is necessary for survival. Where cultural norms are consistently observed, our sense of normality becomes a deeply rooted part of our beliefs, virtually unshakable.
Until someone does something different, like walk on a freeway. Whatever isn't normal is noticed, examined, studied, prosecuted. We simply must understand why the anomaly occurred, so we can correct, punish, or come to accept it; like women wearing pants.
Approximately 90% of the population, throughout the globe and throughout history, is right-handed. This is the norm. Left-handedness is an aberration. It creates discomfort and piques curiosity.
Smits illustrates our dual nature: yes/no, black/white, right/left and disserts on how our dual nature affects, or even creates our perceptions. He evaluates the persistent posits of left-handedness. Mental health issues, criminality, brain damage, in utero trauma, antisocial behavior and more explanations have been put forth, because of our need to address the left-handed phenomenon. He insists that left-handedness is not a problem - for left-handed people, anyway.
He also discusses attempts by cultures to correct left-handedness, and how left-handed people deal with those attempts. He explains the challenges that left-handed people face.
This is an absorbing read, whether you are right- or left-handed. Nearly every question conceivable regarding left-handedness is addressed. This is a rational work with a formidable bibliography, thoroughly researched. I recommend this highly to anyone with an interested in handedness, and especially parents, teachers, and child care providers. Pseudoscience in regard to handedness is prevalent today. This book explains all that away.
