The youth now makes a choice of some trade or employment, and taking up the special and elaborate studies which belong to that, he follows these until his graduation at twenty-one. During these years he is under the direct practical instruction of teachers who are masters or officers in his chosen employment. It will be observed that this system applies and is alike adapted to both sexes.

HIGHER SCHOOLS. The college and the univer

sity have the same plan as here sketched, only it is upon an enlarged scale. Every one of the twelve groups has a male and a female teacher, and over the whole is a president and a presidess.

The special colleges, training students for only one profession, would only require a faculty of thirteen officers.

CULTURE IN MATURITY is provided for in all

the bands by regular courses of lectures and discussions in the department of culture. These cover the ground of art, science and philosophy, with all the new discoveries made from time to time. Thus our education becomes perpetual.

UNITY OF TRUTII. Every truth, every law,

bears a fixed relation to the constitution of man. Therefore when it is once fully understood, it must appear essentially the same to all minds. It is the

k of science to take the phenomena of life, whether these belong to our physical or our spiritual experience, and by classifying, comparing and testing the phenomena, to discover the natural laws under which they were produced. Then we can understand the facts and also see their bearing upon the conditions of happiness.   "

In order to be scientific, the proofs must always be

of such a character that all can understand them alike.

They can thus become the common basis for unity of

social action. We must not impose any doctrine or belief upon any person, and no doctrine or belief which is not susceptible to scientific proof must ever be made a part of the laws or constitution of society.

ORDINARY KNOWLEDGE expresses in a single

formula a particular truth respecting a particular phenomenon.

SCIENCE expresses in a single formula a general truth respecting an entire order of phenomena.

PHILOSOPHY expresses in a single formula a universal truth respecting all phenomena.

ART CONSISTS of rules by which work is to be done. Skill is the mental and physical qualification required for the use of these rules.

All science is practical knowledge, for it is based upon an exact acquaintance with the objects of nature. It differs from other knowledge in possessing system, clearness and certainty, in place of disorder, obscurity and uncertainty.

If we are to accept philosophy as the highest summary of truth, then it is important that its basis be carefully and honestly laid. And because philosophers have done careless and bad work at the very foundations, we must here consider for a moment the fundamental concepts of space, time and the "infinite." The real truth about these is clear and simple when rightly stated.

BASIC PROPERTIES. Every object has form, space

and parts. We express its space by saying it has length, breadth and thickness. This block has,
