This you may say of man - when theories change and crash, when schools, philosophies, when narrow dark alleys of thought, national, religious, economic, grow and disintegrate, man reaches, stumbles forward, painfully, mistakenly sometimes. Having stepped forward, he may slip back, but only half a step, never the full step back.
Equality is the heart and essence of democracy, freedom, and justice, equality of opportunity in industry, in labor unions, schools and colleges, government, politics, and before the law. There must be no dual standards of justice, no dual rights, privileges, duties, or responsibilities of citizenship. No dual forms of freedom.
