Interpretation:

"Judge Benjamin Lindsey talked the talk and walked the walk.  He fought for a more humain judicial system, especially for minors.

Nature demonstrates perfect order and obeys immutable laws.  We can learn from nature if we study it.  Learning the lessons that nature has to teach costs nothing.  Using these lessons in our own lives pays us back for the effort in learning them for the rest of our lives."

Lindsey, Benjamin Barr 1869 -- 1943
Jurist, reformer; born in Jackson, Tenn. The son of a debt-ridden, depressive confederate officer, he moved with his family to Denver, Colo., at age 11. When his father killed himself five years later, he went to work as an office boy for a lawyer; studying in his free time, he was admitted to the Colorado bar in 1894. He became a crusader for the juvenile court movement, pushing through legislation that created the first such court in the U.S.A. As juvenile court judge for more than a quarter-century (1900--27), he held that economic injustice caused crime and that juvenile offenders should be treated rather than punished. He also established the principle that adults may be legally responsible for contributing to the delinquency of a minor. He moved to California in 1928 and became a Superior Court judge in Los Angeles in 1934. In later years he campaigned for sex education, contraception, and the liberalization of divorce laws. His autobiography, The Dangerous Life, appeared in 1931.
