An editorial interpretation.
The speaker credits smoking with a benevolent effect: the smoker's mind turns wise and philosophical, and their conduct grows kind and charitable. It is a fond claim that tobacco makes a person both thoughtful and generous, offered as the speaker's view rather than established fact.
