I'm looking for an introductory text into philosophical inquiry of ethics.
I need this text to be exceedingly accessible (i.e. high school or undergraduate level) but still sufficiently philosophically rigorous.
I would like to use it as a required summer reading for second year philosophy students, so it can assume some basic philosophical background, but I don't want it to be overly technical (i.e. Kantian, lol.)
I'd prefer a text that takes a survey-like approach, probably one that touches upon the three major frameworks: virtue ethics, consequentialism, and deontology. Any suggestions?
