LEFT ROYLE 135 RUBBER he was appointed Professor of Philos- ophy in Paris, and exercised an immense influence on the philosophy of France. Rejecting the purely sensuous system of Condillac, he gave special prominence to the principles of the Scotch school of Reid and Stewart. Strongly "spiritual- ist" as opposed to materialism, he orig- inated the "Doctrinaire" school, of which Jouffroy and Cousin were the chief rep- resentatives. He was appointed presi- dent of the Commission of Public In- struction in 1815, but resigned that post in 1820; in 1825 also he returned to political life as deputy for the depart- ment of Marne. The French Academy opened its doors to him in 1827; and in 1828 he was named president of the Chamber of Representatives, and in that capacity presented the address of the 221 deputies (March, 1830) withdrawing their support from the government, which the king refused to hear read. Next day the Chamber was prorogued. From 1842 Royer-Collard completely withdrew from public life. His salon was latterly the resort of such men as Cousin, Guizot, De Broglie, Casimir Pe- rier, Villemain, De Remusat, and others. He never was a writer, and he became a philosopher only by accident; his true interest in life was politics, his real emi- nence as a political orator after the ancient pattern rather than that of the modern parliamentary debater. He died in his country seat, Chateauvieux, near St. Aignan, Loir-et-Cher, Sept. 4, 1845. ROYLE, EDWIN" MILTON, an Ameri, can dramatist and actor, born at Lex- ington, Mo., in 1862.
