Review – Our Three-Step Pie • We begin by using this to dissect our problem • But… How do we then define our moral (ethical) problems / questions?
Genesis of Ethical Thought • Began in ancient Greece • Influenced by religion • Current theories derive from western culture: • Europe • Middle East Source: socialstudiesforkids.com Engineers are used to having just ONE theory to solve problems. Alas, ethics is not that simple. There are many theories to consider concurrently!
Do Not Panic! • MORAL THEORY • Defines issues in UNIFORM ways • Links ideas and problems together in CONSISTENT ways
Maximize well-being of society as a whole, rather than the individual • Produce most utility • Take consequences of everyone involved into account • Consider construction a dam Balance between good and bad consequences of action • Utilitarianism • (John Stuart Mill)
