Concision in style, precision in thought, decision in life.
— Victor Hugo

Brevity and conciseness are the parents of correction.
Hosea Ballou concise quote

In labouring to be concise, I become obscure.
— Horace

In all pointed sentences, some degree of accuracy must be sacrificed to conciseness.
— Samuel Johnson

Despots play their part in the works of thinkers. Fettered words are terrible words. The writer doubles and trebles the power of his writing when a ruler imposes silence on the people. Something emerges from that enforced silence, a mysterious fullness which filters through and becomes steely in the thought. Repression in history leads to conciseness in the historian, and the rocklike hardness of much celebrated prose is due to the tempering of the tyrant.
— concise quotation by Victor Hugo
