The Ideals of Ruby’s Creator
Ruby is a language of careful balance. Its creator, Yukihiro “matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Building on this, he adds:
Ruby is simple in appearance, but is very complex inside, just like our human body.
