Save to active project


DURING recent years the approach to psychology from the point of view of "needs" has been gaining ground.1 The idea of needs has not only been of value in connecting various fields of investigation, which were formerly isolated, but has also led to new questions arising in present researches, which is of still greater importance. The concept of need in comparison with that of drive has the advantage of being nearer to reality, and assuredly is much less encumbered with hypotheses than is the concept of instinct. For the present it is, of course, impossible to work in animal psychology without the postulation of instincts, because they are necessary for the classification of certain forms of behaviour, but all those who understand the situation complain of the irritating sterility of this concept in any approach to new problems. It will be found, as a matter of fact, that the idea of needs will prove helpful in our attempt to find new explanations for certain types of instinctive behaviour.
