What reading level is Organic Evolution As the Result of the Inheritance of Acquired Characters Accord book?
To quickly assess the difficulty of the text, read a short excerpt:
" Impulse and Instinct Although we may rightly talk of the instinct of seeking food in higher animals, it is impossible among the lower to establish a limit above which the taking of food is influenced by a choice due to nervous action. In the same way such a limit cannot be established for the commencement of the sexual instinct ; indeed, in my opinion, the commencement of sexual activity depends ultimately on processes of nutrition.
^ Cf. The next section.
302 MENTAL FACULTIES sec.
Since all ...nervous action must have been gradually evolved through relations of the organism to the outer world, the diffi- culties referred to lie in the nature of the case, and can there- fore only be considered as in favour of the justice of the view I advocate. But these difficulties constantly make themselves felt to an uncomfortable degree in the attempt to distinguish between impulse and instinct. Ought we really to describe the sexual impulse as an instinct ? Certainly it has as much right to be so called as the migratory impulse, which appears in spring and autumn, even in birds which have been reared and kept all their lives in cages.
