Quote by Henry David Thoreau
Whatever my own practice may be, I have no doubt that it is a part of the destiny of the human race, in its gradual improvement, to leave off eating animals, as surely as the savage tribes have left off eating each other when they came in contact with the more civilized.
Summary
This quote suggests that the progression of humanity inevitably leads towards a time when consuming animals will no longer be a part of our dietary habits. It draws a parallel between the advancement of human civilizations, transitioning from practices such as cannibalism to civilized norms, and envisions a future where the same progression will lead to the abandonment of eating animals. The quote alludes to the belief that the collective evolution of society will eventually result in a widespread adoption of vegetarian or vegan practices.
