Instinct is said to be blind—that is, either the end is not consciously recognized by the animal, or the connection of the means with the end is not understood. Instinct is also, in general, somewhat deficient in instant adaptability to extraordinary circumstances.

Examples
“Thus, if we consider only those typical cases in which the complete triumph of intelligence and of instinct is seen, we find this essential difference between them: _instinct perfected is a faculty of using and even of constructing organized instruments; intelligence perfected is the faculty of making and using unorganized instruments_.”
“Let us adopt then words sanctioned by usage, and give the distinction between intelligence and instinct this more precise formula: _Intelligence, in so far as it is innate, is the knowledge of a_ form; _instinct implies the knowledge of a_ matter.”
“Once upon a time, the term instinct was perfect way to explain things that we didn't completely understand at the time.”
“To apply the term instinct to the regular and involuntary movements of the bodily organs, such as the beating of the heart and the action of the organs of respiration, is manifestly an extension of the ordinary acceptation of the term.”
“This wisdom is often classed by the unknowing under the term instinct, whereas it displays no less skill and knowledge than that of our modern surgery.”
“As we breed animals for the transmission of physical attributes, so the Kaldanes breed themselves for the transmission of attributes of the mind, including memory and the power of recollection, and thus have they raised what we term instinct, above the level of the threshold of the objective mind where it may be commanded and utilized by recollection.”
“McDougall obviously employs the term instinct in a much more comprehensive and inclusive sense than Shand does.”
“There is a growing tendency in biology and comparative psychology to restrict the term instinct to inherited purposive adaptations.”
“In both popular and scientific literature the term instinct has been given such a variety of meanings that it is not possible to frame for it an adequate definition which would meet with general acceptance.”
“Kaldanes breed themselves for the transmission of attributes of the mind, including memory and the power of recollection, and thus have they raised what we term instinct, above the level of the threshold of the objective mind where it may be commanded and utilized by recollection.”
