Slavery does not merely mean a legalised form of subjection.
It means a state of society in which some men are forced to accept from others the purposes which control their conduct.

Unlike a drop of water which loses its identity when it joins the ocean,
man does not lose his being in the society in which he lives.
Man's life is independent.
He is born not for the development of the society alone, but for the development of his self too.

This condition obtains even where there is no slavery in the legal sense. It is found where as in caste system, some persons are forced to carry on the prescribed callings which are not their choice.

A great man is different from an eminent one in that he is ready to be the servant of the society.

Religion and slavery are incompatible.

Justice has always evoked ideas of equality, of proportion of compensation.
Equity signifies equality. Rules and regulations, right and righteousness are concerned with equality in value.
If all men are equal, then all men are of the same essence, and the common essence entitles them of the same fundamental rights and equal liberty...

In short justice is another name of liberty, equality and fraternity.
