Excerpt

The topic of mental levels or "levels of intelligence" has been chosen for these lectures because while the subject is not altogether new it seems that there are phases of it that have not been dwelt upon but which enable us to look at some of the present day problems from a new angle, and suggest solutions different from any usually discussed.

Stated in its boldest form our thesis is that the chief determiner of human conduct is a unitary mental process which we call intelligence: that this process is conditioned by a nervous meehanism that is inborn: that the degree of efficiency to be attained by that nervous mechanism and the consequent grade of intelligence or mental level for each individual is determined by the kind of chromosomes that come together with the union of the germ cells: that it is but little affected by any later influence except such serious accidents as may destroy part of the mechanism.

As a consequence any attempt at social adjustment which fails to take into account the determining character of the intelligence and its unalterable grade in each individual is illogical and inefficient.
