Part 6 Ethics

Chapter 37 The Common Good

Section c. Love with Order

The good of internal order is attained when one loves each created good as one ought, namely in accordance with justice, by bringing the intelligence into the feelings and emotions. This describes the relation between mercy and justice, truth and love, the mind and the heart.

Without this, love is always tended towards disorder, to sentimentality and imbalances of ordination caused by favouritism and arbitrary feelings. 

According to Saint Thomas the relations would be as follows:

Love of God includes love of neighbour and love of oneself but surpasses them. The love of neighbour does not include the love of God, but without it it would always be disordered and not pure love. It does include the love of self but surpasses it. The love of self does not include the love of neighbour or the love of God, but without both it would always be an egotistical, prideful love, and therefore tending one away from both love and goodness.
