0 To Our Venerable Brethren the Patriarchs, Primates, Archbishops, Bishops, and other Ordinaries in Peace and Communion with the Apostolic See. The grave discussions on economical questions which for same time past have disturbed the peace of several countries of the world are growing in frequency and intensity to such a degree that the minds of thoughtful men are filled, and rightly so, with worry and alarm. These discussions take their rise in the bad philosophical and ethical teaching which is now widespread among the people. The changes, also, which the mechanical inventions of the age have introduced, the rapidity of communication between places, and the devices of every kind for diminishing labor and increasing gain, all add bitterness to the strife; and, lastly, matters have been brought to such a pass by the struggle between capital and labor, fomented as it is by professional agitators, that the countries where these disturbances most frequently occur find themselves confronted with ruin and disaster.
