In this paper we present an approach towards safe software composition based on aspect-orientation. Aspects enable the systematic addition of code into existing programs but often they also introduce er- rors. In order to provide safe aspects for software composition we address the verification of the aspect-oriented language paradigm. We construct a basic calculus for aspects with types and prove formally type safety. More precisely, this paper presents the following contributions (a) a fully formalized type system for the Theory of Objects including the proof of type safety, (b) a theory of aspects based on the Theory of Objects including a type system for aspects, and (c) the definition of a notion of type safety for aspects including its proof. The entire theory and proofs are carried out in the theorem prover Isabelle/HOL.
