The advantage of pure, and the disadvantage of impure air are experienced each time we breathe, and all who understand the causes of disease know tha… - Robert Owen

All that is now requisite, previous to withdrawing the last mental bandage by which hitherto the human race has been kept in darkness and misery, is, by calm and patient reasoning to tranquillize the public mind, and thus prevent the evil effects which otherwise might arise from the too sudden prospect of freely enjoying rational liberty of mind. To withdraw that bandage without danger, reason must be judiciously applied to lead men of every sect (for all have been in part abused to reflect that if untold myriads of beings, formed like themselves, have been so grossly deceived as they believe them to have been, what power in nature was there to prevent them from being equally deceived? Such reflections, steadily pursued by those who are anxious to follow the plain and simple path of reason, will soon make it obvious that the inconsistencies which they behold in all other sects out of their own pale, are precisely similar to those which all other sects can readily discover within that pale. It is not, however, to be imagined, that this free and open exposure of the gross errors in which the existing generation has been instructed, should be forthwith palatable to the world; it would be contrary to reason to form any such expectations. Yet, as evil exists, and as man cannot be rational, nor of course happy, until the cause of it shall be removed; the writer, like a physician who feels the deepest interest in the welfare of his patient, has hitherto administered of this unpalatable restorative the smallest quantity which he deemed sufficient for the purpose. He now waits to see the effects which that may produce. Should the application not prove of sufficient strength to remove the mental disorder, he promises that it shall be increased, until sound health to the public mind be firmly and permanently established.

The advanced members of the medical profession know that the health of society is not to be obtained or maintained by medicines; — that it is far better, far more easy and far wiser, to adopt substantive measures to prevent disease of body or mind, than to allow substantive measure to remain continually to generate causes to produce physical and mental disorders.

The end of government is to make the governed and the governors happy. That government then is thebest, which in practice produces the greatest happiness to the greatest number; including those who govern, and those who obey.
