The time has gone by when any one man could hope to write an adequate text book of psychology. The science has now so many branches, so many methods, so many fields of application, and such an immense mass of data of observation is now on record, that no one man can hope to have the necessary familiarity with the whole. But, even when a galaxy of learning and talent shall have written the text book of the future, there will still be need for the book which will introduce the student to his science, which will aim at giving him at the outset of his studies a profitable line of approach, a fruitful way of thinking of psychological problems, and a terminology as little misleading as possible. The present volume is designed to render these services.

Now = P (in circular measure), r'-r = r (in circular measure);.'. r: r':: P: P', or (radius of earth): (radios of moon):: (moon's parallax): (moon's semidiameter). Examples. 1. Taking the moon's horizontal parallax as 57', and its angular diameter as 32', find its radius in miles, assuming the earth's radius to be 4000 miles. Here moon's semidiameter = 16';.-. 4000::: 57': 16';.-. r = 400 16 = 1123 miles. 2. The sun's horizontal parallax being 8"8, and his angular diameter 32V find his diameter in miles. ' Am. 872,727 miles. 3. The synodic period of Venus being 584 days, find the angle gained in each minute of time on the earth round the sun as centre. Am. l"-54 per minute. 4. Find the angular velocity with which Venus crosses the sun's disc, assuming the distances of Venus and the earth from the sun are as 7 to 10, as given by Bode's Law. Since (fig. 50) S V: VA:: 7: 3. But Srhas a relative angular velocity round the sun of l"-54 per minute (see Example 3); therefore, the relative angular velocity of A V round A is greater than this in the ratio of 7: 3, which gives an approximate result of 3"-6 per minute, the true rate being about 4" per minute. Annual ParaUax. 95. We have already seen that no displacement of the observer due to a change of position on the earth's surface could apparently affect the direction of a fixed star. However, as the earth in its annual motion describes an orbit of about 92 million miles radius round the sun, the different positions in space from which an observer views the fixed stars from time to time throughout the year must be separated ...

Outline of Theoretical Psychology discusses basic philosophical problems in the discipline and profession of psychology. The author addresses such topics as what it means to be human in psychology; how psychological knowledge is possible and what it consists of; the role of social justice in psychology; and how aesthetic experience could help us to understand the human condition. Proposing possible solutions to a range of such issues, Thomas Teo situates theoretical questions within traditional branches of philosophical inquiry: ontology, epistemology, ethics, and aesthetics. This book argues that in order to improve psychology as a discipline and in practice, psychologists must reconceive the unit of psychological analysis, looking beyond individual capacity and even experience. By engaging with these basic philosophical problems, Teo demonstrates how psychology can avoid its common pitfalls and continue as a force for resistance and the good.
