POSITIVE SOCIETY 323 POSTAGE STAMPS matics (number, geometry, mechanics), astronomy, physics, chemistry, biology, and sociology. It relinquishes attempts to transcend the sphere of experience, and seeks to establish by observation and induction laws or constant relations, and resigns iself to ignorance of the agents. In the opinion of its founder it is cap- able of being developed into a religion and a polity. POSITIVE SOCIETY, a society found- ed in Paris in 1848, by Comte, in the hope that it might exert as powerful an influence over the revolution as the Ja- cobin Club had exerted in 1789. In this he was disappointed, but the disciples who gathered around him were the germ of the Positivist Church. POSITIVISM, the religion of Human- ity, developed from the positive philos- ophy, and claiming to be a synthesis of all human conceptions of the external order of the universe. Its professed aim, both in public and private life, is to se- cure the victory of social feeling over self-love, of altruism over egotism.

POSTAGE STAMPS, a term employed to indicate not really a stamp or impres- sion, but a printed label pasted on pack- ages and letters to show that the cost of carriage has been already paid. Such stamps may be issued by the govern- ment or by carrying companies.

The two main divisions are adhesive stamps and stamps actually engraved in the envelope. The adhesives are placed on the matter to be delivered, and this has been the method in vogue since 1840, when Row- land Hill conceived his uniform Penny Postage plan and succeeded in having it established in Great Britain. Up to that time it had been the custom to charge for the transportation of letters and pack- ages in proportion to the distance cov- ered, and these charges often mounted to a considerable sum, such as "twelve pence" or 24 cents for a distance of 250 miles. The charges were also usu- ally not prepaid, and there was frequent loss to the carrying company in cases of refusal of payment on the part of the addressee. The great growth in cor- respondence which followed the innova- tion and the trifling cost involved in the production of stamps guaranteed its suc- cess from a financial point of view from the start. The use of the prepaid stamp speedily spread to other countries, and was gradu- ally taken up by the governments of the different nations with the assumption by these governments of the national
