Only when...

Only when things are investigated is knowledge extended; 
only when knowledge is extended are thoughts sincere; 
only when thoughts are sincere are minds rectified; 
only when minds are rectified are the characters of persons cultivated; 
only when character is cultivated are our families regulated; 
only when families are regulated are states well governed; 
only when states are well governed is there peace in the world.
