Chapter Silverback to Simple of S by Webster's Dictionary (1913 Edition)

11. (Chem.) Not capable of being decomposed into anything more simple or ultimate by any means at present known; elementary; thus, atoms are regarded as simple bodies. Cf. Ultimate, a.

A simple body is one that has not as yet been decomposed. There are indications that many of our simple elements are still compound bodies, though their actual decomposition into anything simpler may never be accomplished.

12. (Min.) Homogenous.

13. (Zoöl.) Consisting of a single individual or zooid; as, a simple ascidian; — opposed to compound.

Simple contract (Law), any contract, whether verbal or written, which is not of record or under seal. J. W. Smith. Chitty. — Simple equation (Alg.), an equation containing but one unknown quantity, and that quantity only in the first degree. — Simple eye (Zoöl.), an eye having a single lens; — opposed to compound eye. — Simple interest. See under Interest. — Simple larceny. (Law) See under Larceny. — Simple obligation (Rom. Law), an obligation which does not depend for its execution upon any event provided for by the parties, or is not to become void on the happening of any such event. Burrill.

Syn. — Single; uncompounded; unmingled; unmixed; mere; uncombined; elementary; plain; artless; sincere; harmless; undesigning; frank; open; unaffected; inartificial; unadorned; credulous; silly; foolish; shallow; unwise. — Simple, Silly. One who is simple is sincere, unaffected, and inexperienced in duplicity, — hence liable to be duped. A silly person is one who is ignorant or weak and also self- confident; hence, one who shows in speech and act a lack of good sense. Simplicity is incompatible with duplicity, artfulness, or vanity, while silliness is consistent with all three. Simplicity denotes lack of knowledge or of guile; silliness denotes want of judgment or right purpose, a defect of character as well as of education.

I am a simple woman, much too weak
To oppose your cunning.

Shak.

He is the companion of the silliest people in their most silly pleasure; he is ready for every impertinent entertainment and diversion.

Law.
