The real object of education is to give children resources that will endure as long as life endures; habits that time will ameliorate, not destroy; occupation that will render sickness tolerable, solitude pleasant, age venerable, life more dignified and useful, and death less terrible.

Meaning: Death is possible at any age, while old age makes the end of life impossible to ignore. The contrast is a reminder of mortality.

Meaning: Even a very long life has an end. The superlative “longest” removes the possibility of escaping mortality simply by outliving others.

Meaning: The timing of death cannot be treated as an appointment people can count on controlling. The calendar image expresses uncertainty about life’s duration, encouraging awareness of limits without making a prediction about any individual or demanding constant urgency.

Meaning: Death is imagined as unable to hear objections, so a protest cannot make it negotiate. The saying expresses mortality’s finality rather than a judgment about how someone should feel about loss.
