William Hazlitt's purpose in writing this passage was to enlighten the reasons of why with so much tragedy and despair around us we are still able to feel happiness or laugh at a poorly told joke.
Hazlitt's tone is a mixture of condescending and explanation. The passage is written to explain our faults and why we at times express or feel stronger emotions for events, or actions that have some humor. However, at the same time, there is an event or action that is very sad that the emotions produced should be greater, although, they are not. In sight of something of great remorse, we will laugh at something insignificant before we would express remorse. Hazlitt patronizes people in general for laughing at nothing, and for not crying at something tragic. We as humans have the capacity to feel and express strong emotions, both positive and negative, yet we only express the positive emotions, or only allow ourselves to feel the positive emotions.
