“[Walter even gave the tortoises a mock-biological name, Machina speculatrix] because they illustrate particularly the exploratory, speculative behaviour that is so characteristic of most animals.”

“If an ɑ-machine prints two kinds of symbols, of which the first kind (called figures) consists entirely of 0 and 1 (the others being called symbols of the second kind), then the machine will be called a computing machine.”

“Machines deprive us of two things which are certainly important ingredients of human happiness, namely, spontaneity and variety.”

“A homeostat constantly seeks to establish a balance which is perpetually disrupted, and performs a statistical exploration of all the possible combinations of inputs.
The actual research on the apparatus is guided by a triple determinism which integrates:
#. one element of uncertainty created by an "indifferent cell," which systematically makes use of chance;
#. one element of "sensorial reactions" which integrates the effects of the sound atmosphere, of the light atmosphere and of the heat atmosphere;
#. an "internal determinism" created by the feedbacks of the various active chains among one another, in order to liberate the machine progressively. Its degree of liberty can easily be modified.
The objective sought is above all of an experimental order. As for electronic animals, the synthesis of the faculties must be effected very gradually, and the behavior of the "models" man makes of himself must be observed. This exploration by the "models" of physiology, psychology and sociology marks the opening of a new path in research.”

“The sense in which an automatic door "understands instructions" from its photoelectric cell is not at all the sense in which I understand English.”

“Animals are not machines; one of my main concerns is to combat this notion. Actually only machines are machines.”

Mary Midgley (1919–2018) British philosopher and ethicist

Introduction, Beast and Man: The Roots of Human Nature (1979).
Context: Consideration of motives brings up the matter of free will. I had better say once, that my project of taking animal comparisons seriously does not involve a slick mechanistic or deterministic view of freedom. Animals are not machines; one of my main concerns is to combat this notion. Actually only machines are machines.

“The real question is not whether machines think but whether men do. The mystery which surrounds a thinking machine already surrounds a thinking man.”

“When taken as a way of modeling cognitive architecture, connectionism really does represent an approach that is quite different from that of the classical cognitive science that it seeks to replace. Classical models of the mind were derived from the structure of Turing and Von Neumann machines. They are not, of course, committed to the details of these machines as exemplified in Turing's original formulation or in typical commercial computers—only to the basic idea that the kind of computing that is relevant to understanding cognition involves operations on symbols.. In contrast, connectionists propose to design systems that can exhibit intelligent behavior without storing, retrieving, or otherwise operating on structured symbolic expressions. The style of processing carried out in such models is thus strikingly unlike what goes on when conventional machines are computing some function.”

“The human creature represents the most perfect thinking and acting machine yet evolved on this earth, developing through countless ages in strict harmony with the surrounding conditions of temperature, atmosphere, light, and gravitation.”

William Crookes (1832–1919) British chemist and physicist

Address to the Society for Psychical Research (1897)
Context: The human creature represents the most perfect thinking and acting machine yet evolved on this earth, developing through countless ages in strict harmony with the surrounding conditions of temperature, atmosphere, light, and gravitation. The profound modifications in the human frame, which any important alteration in either of these factors would occasion, are strangely unconsidered. It is true there have been questionings as to the effects that might be occasioned by changes in temperature and atmospheric composition, but possible variations in gravitation seem almost to have escaped notice. The human body, which long experience and habit have taught us to consider in its highest development as the perfection of beauty and grace — "formed in the image of God " — is entirely conditioned by the strength of gravitation on this globe. So far as has been possible to ascertain, the intensity of gravity has not varied appreciably within those geologic ages covering the existence of animated thinking beings.
