  Understanding our laws will also help us to see which aspects of them are genuinely in need of reform, and how these reforms might be accomplished. For instance, Montesquieu believes that the laws of many countries can be made be more liberal and more humane, and that they can often be applied less arbitrarily, with less scope for the unpredictable and oppressive use of state power. Likewise, religious persecution and slavery can be abolished, and commerce can be encouraged. These reforms would generally strengthen monarchical governments, since they enhance the freedom and dignity of citizens. If lawmakers understand the relations between laws on the one hand and conditions of their countries and the principles of their governments on the other, they will be in a better position to carry out such reforms without undermining the governments they seek to improve.
