The power of languages is rooted in composition. An infinite number of sentences can be composed from a finite set of generative rules. The more uniformly the rules apply, the more valid compositions there are. Hence simpler rules give rise to richer discourse - a case of ‘less is more’. We must however be careful as to which distinctions we preserve and which we eliminate. If we abstract too much we risk creating an undifferentiated soup with no landmarks to orient us.

A uniform space of objects with simple rules governing their interaction is an obvious example of these ideas, but objects also serve as a cautionary tale. Achieving simplicity is not easy; it requires taste, judgement, experience and dedication. Ingenuity is essential as well, but left unchecked, it often leads to uncontrollable complexity. The path of least resistance follows the tautological principle that ‘more is more’, and who can argue with a tautology? Dissonance dominates.

I will endeavour to illustrate these rather abstract principles by means of examples from my own work and that of others, in programming languages, software and other domains. We may speak of many things - mixins, modules and memory, graphics and generics, patterns and parsers, architecture and automobiles, objects or other things entirely.

Gilad Bracha is the creator of the Newspeak programming language and a software engineer at Google where he works on Dart. Previously, he was a VP at SAP Labs, a Distinguished Engineer at Cadence, and a Computational Theologist and Distinguished Engineer at Sun. He is co-author of the Java Language Specification, and a researcher in the area of object-oriented programming languages. Prior to joining Sun, he worked on Strongtalk, the Animorphic Smalltalk System. He received his B.Sc in Mathematics and Computer Science from Ben Gurion University in Israel and a Ph.D. in Computer Science from the University of Utah.
