Samuel Smiles：Thrift, Excerpt 136

The physiologist may discuss the laws of health, and the Board of Health may write tracts for circulation among the people; but half the people cannot so much as read; and of the remaining half, but a very small proportion are in the habit of _thinking_. Thus the laws of health are disregarded; and when fever comes, it finds a wide field to work upon: in undrained and filthy streets and back-yards,--noisome, pestilential districts,--foul, uncleansed dwellings,--large populations ill-supplied with clean water and with pure air. There death makes fell havoc; many destitute widows and children have to be maintained out of the poor's-rates; and then we reluctantly confess to ourselves that Ignorance is Power.
