  There is not, in my opinion, anything more mysterious in nature than this instinct in animals, which thus rises above reason and falls infinitely short of it. It cannot be accounted for by any properties in matter, and at the same time works after so odd a manner that one cannot think it the faculty of an intellectual being. For my own part, I look upon it as upon the principle of gravitation in bodies, which is not to be explained by any known qualities inherent in the bodies themselves, nor from the laws of mechanism, but, according to the best notions of the greatest philosophers, is an immediate impression from the first mover, and the divine energy acting in the creatures.
Joseph Addison: Spectator, No. 120.    
  Reason shows itself in all occurrences of life; whereas the brute makes no discovery of such a talent, but in what immediately regards his own preservation or the continuance of his species. Animals in their generation are wiser than the sons of men; but their wisdom is confined to a few particulars, and lies in a very narrow compass. Take a brute out of his instinct, and you find him wholly deprived of understanding.
Joseph Addison: Spectator, No. 120.    
  When a hen has laid her eggs so that she can cover them, what care does she take in turning them frequently, that all parts may partake of the vital warmth!
Joseph Addison.    
  The male bird amuses the female with his songs during the whole time of her sitting.
Joseph Addison.    
  Speech must come by hearing and learning; and birds give more heed, and mark words more, than beasts.
Francis Bacon.    
  That which acts for an end unknown to itself, depends upon some overruling wisdom that knows that end. Who should direct them in all those ends, but He that bestowed a being upon them for those ends; who knows what is convenient for their life, security, and propagation of their natures? An exact knowledge is necessary both of what is agreeable to them, and the means whereby they must attain it, which, since it is not inherent in them, is in that wise God who puts those instincts into them, and governs them in the exercise of them to such ends.
Stephen Charnock: Attributes.    
  All creatures have a natural affection to their young ones; all young ones by a natural instinct move to, and receive, the nourishment that is proper for them; some are their own physicians, as well as their own caterers, and naturally discern what preserves them in life, and what restores them when sick. The swallow flies to its celandine, and the toad hastens to its plantain. Can we behold the spider’s nets, or silkworm’s web, the bee’s closets, or the ant’s granaries, without acknowledging a higher being than a creature who hath planted that genius in them?
Stephen Charnock: Attributes.    
  No sound philosopher will confound instinct with reason because an orang outang has used a walking-stick, or a trained elephant a lever. Reason imparts powers that are progressive, and that, in many cases, without any assignable limit; instinct only measures out faculties that arrive at a certain point and then invariably stand still. Five thousand years have added no improvement to the hive of the bee, nor to the house of the beaver; but look at the habitations and the achievements of man.
Charles Caleb Colton: Lacon.    
  To the present impulses of sense, memory, and instinct, all the sagacities of brutes may be reduced; though witty men, by analytical resolution, have chymically extracted an artificial logic out of all their actions.
Sir Matthew Hale.    
  The sagacities and instincts of brutes, the spontaneousness of many of their animal motions, are not explicable without supposing some active determinate power connected to and inherent in their spirits, of a higher extraction than the bare natural modification of matter.
Sir Matthew Hale.    
  Implanted instincts in brutes are in themselves highly reasonable and useful to their ends, and evincible by true reason to be such.
Sir Matthew Hale.

John Locke.    
  Birds learning tunes, and their endeavours to hit the notes right, put it past doubt that they have perception, and retain ideas, and use them for patterns.
John Locke.    
Sir Isaac Newton.    
  An instinct is a propensity prior to experience, and independent of instruction.
William Paley.    
  Every animal is providentially directed to the use of its proper weapons.
John Ray.    
  Beasts, birds, and insects, even to the minutest and meanest of their kind, act with the unerring providence of instinct; man, the while, who possesses a higher faculty, abuses it, and therefore goes blundering on. They, by their unconscious and unhesitating obedience to the laws of nature, fulfil the end of their existence; he, in wilful neglect of the laws of God, loses sight of the end of his.
Robert Southey.    
Richard Whately.
