INSTINCT AND REASON. 131 



It appears to me, in the present state of our knowledge 

 of tlie inter-relations of, or confusion between, instinct and 

 reason, convenient at least to assume that certain instincts 

 are congenital, certain mental powers natural, innate, or 

 instinctive. Such, for instance, are to be regarded the 

 following instincts or groups thereof : 



1. The more purely physical ones of 



a. Hunger and thirst, including the so-called predatory 

 or prey-catching instinct. 



1. Self-preservation, or the love of life, including self- 

 defence and self-protection. 



c. Pleasure and pain. 



d. Sense of existence. 



e. Physical comfort, such as that arising from warmth. 

 /. Play or sport playfulness, sportiveness, or friskiness 



in the young. 

 g. Migration. 

 h. 'Feeling of need of shelter or covering. 



2. Those connected with external sensorial impressions, 

 such as 



a. Weather-forecasting. 



6. Sense of locality and direction, with perhaps the power 

 of way-finding. 



3. Those connected with the sexual appetite, including 

 pairing, propagation, and incubation. 



4. Those connected with the social or family relationships, 

 including 



a. Adhesiveness, or the tendency to form attachments to 

 person or place. 



I. Love of society or companionship. 



c. Longing for love and being loved, including maternal, 

 parental, filial, and fraternal longings, yearnings, or affec- 

 tion. 



d. Sympathy, compassion, or pity, charity or benevolence, 

 with their opposites. 



5. Destructiveness, including cruelty. 



6. Acquisitiveness the accumulation of property. 



7. Combativeness. 



8. Selfishness.
