 Hutcheson emphasises both the complexity of the relations between our natural affections and also the need, in the name of morality, to exercise careful management of the relations between the affections. We must especially be careful not to let any of our affections get too ‘passionate’, for a passionate affection might become an effective obstacle to other affections that should be given priority. Above all the selfish affections must not be allowed to over-rule ‘calm universal benevolence’.
