I do not know that any writer has supposed that on this earth man will ultimately be able to live without food.

The most effectual encouragement to population is, the activity of industry, and the consequent multiplication of the national products.

The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race.

It is an acknowledged truth in philosophy that a just theory will always be confirmed by experiment.

The superior power of population cannot be checked without producing misery or vice.

Had population and food increased in the same ratio, it is probable that man might never have emerged from the savage state.
