ANTS AND SOME OTHER INSECTS. 33 



THE REALM OF FEELING. 



It may perhaps sound ludicrous to speak of feelings in insects. 

 But when we stop to consider how profoundly instinctive and 

 fixed is our human life of feeling, how pronounced are the emotions 

 in our domestic animals, and how closely interwoven with the im- 

 pulses, we should expect to encounter emotions and feelings in 

 animal psychology. And these may indeed be recognised so clearly 

 that even Uexkuell would have to capitulate if he should come to 

 know them more accurately. We find them already interwoven 

 with the will as we have described it. Most of the emotions of in- 

 sects are profoundly united to the instincts. Of such a nature is 

 the jealousy of the queen bee when she kills the rival princesses, 

 and the terror of the latter while they are still within their cells ; 

 such is the rage of fighting ants, wasps, and bees, the above-men- 

 tioned discouragement, the love of the brood, the self-devotion of 

 the worker honey-bees, when they die of hunger while feeding their 

 queen, and many other cases of a similar description. But there 

 are also individual emotions that are not compelled altogether by 

 instinct, e. g., the above-mentioned mania of certain ants for mal- 

 treating some of their antagonists. On the other hand, as I have 

 shown, friendly services (feeding), under exceptional circum- 

 stances, may call forth feelings of sympathy and finally of partner- 

 ship, even between ants of differents species. Further than this, 

 feelings of sympathy, antipathy, and anger among ants may be in- 

 tensified by repetition and by the corresponding activities, just as 

 in other animals and man. 



The social sense of duty is instinctive in ants, though they ex- 

 hibit great individual, temporary, and occasional deviations, which 

 betray a certain amount of plasticity. 



PSYCHIC CORRELATIONS. 



I have rapidly reviewed the three main realms of ant-psychol- 

 ogy. It is self-evident that in this matter they no more admit of
