Ross collected his own aphorisms in a card index. By the time we scanned them, the original cards were rather mixed up. We have done our best to regroup them into the following categories:

  1. On Science
  2. On Evolution
  3. On The Brain
  4. On Learning
  5. On Psychology
  6. On Intelligence
  7. On Computers
  8. On Organisation

In the following list, a blue box indicates that there is an index card for the aphorism, which in some cases contains a less refined version than the one from another source. Hovering the mouse pointer over the box or clicking on it will disply the original index card. Aphorisms without a blue box were collected from other sources, for example, from his students, these are often refined variations of a version on the cards.

    On Science Top

  1. A Cyberneticist observes what might have happened but did not.
  2. A "system" is a set of variables sufficiently isolated to stay [constant] long enough for us to discuss it.
  3. When we take the ordinates of a wave function and use them to compute their exact values a moment later, we are:
    (1) Demonstrating that the science of quantum physics use determinant systems.
    (2) Treating the system as determinate.
  4. Science is the "Observer's Digest".

    On Evolution Top

  5. The species is fundamentally aimless (it finds its goals as it goes along).
  6. By the time sexual reproduction has been achieved, the main difficulty of evolution is past.
  7. The brain is merely Nature's latest means of self-preservation.

    On Man

  8. Division of the world's system into Natural and Man-made died with Darwin.
  9. Man is not the measure: first comes the measure, then we see where he falls; so far the result has always been humiliating.
  10. Man pays for his knowledge with humiliation.

    On Goals

  11. The goals in evolution are what the species has been forced to.
  12. The goals of a species (such as Homo) are what natural selection has driven it to.

    Instincts of Homo

  13. This species is peculiar in that members make an ever-recurrent habit of attacking and exterminating weaker groups of their own species.

    On the evolution of Homo sapiens

  14. For ninety nine hundredths of this time (before any traces of town dwelling) he improved chiefly in his efficiency in killing big game and other branches of his own species.
  15. The specially human part of the brain has been evolved for the chase and for tribal warfare. The final evolution allowed armies of continental size to massacre on a continental scale.
  16. Is my/your life achieving the full potentialities of carbon ?

    On long-term planning in the brain and Man's ability to plan

  17. The brain is wholly opportunist, no less when it proposes a long term plan.

  18. What Homo knows at any moment, of the actual future is absolutely nothing.
  19. Every prediction is an operation on the past (Wiener)

    On Essential Variables

  20. Poor M. Jourdain! He now has to understand that he has been behaving homeostatically all his life, when he thought he was merely minding his business.

    On adaptation

  21. In this universe, the life-time of a planet is only sufficient to allow its evolved life-forms to explore the possibilities of additive adaptation.

    On adaptation as a whole to a whole

  22. All our adaptations are collections of nearly independent bits; life is too short to allow us to explore the really holistic.

    On Progress in adaptation

  23. A brain can improve till it fits its environment:
  24. Man lives by surviving.
  25. Every operation seeks the state that makes it impotent.
  26. A "machine" is a shadow of simple succession.

    On The Brain Top

  28. The brain is natures latest and ferocious instrument of self preservation.
  29. The brain has no brain inside to guide it.
  30. Every one of the faculties boasted of by Man can become a humiliating or fatal embarrassment when the environment is not the usual type.
  31. The man who speaks today of free will is merely a oratory confusionist.
  32. The man who talks of free will in the 60's is trying to pump fog into a situation that he fears is clearing.
  33. In the 60's, to introduce the topic of __ is to introduce fog into a clarifying situation.
  34. Man can remember only those things that natural selection has arranged that he should.
  35. A concept is that which which survives, is stable under a sequence of operations.
  36. The brain takes information from where it is useless and moves it to where it is useful.

  40. As God has to monitor his actions ("And He saw the light that it was good"), so must the brain monitor it.
  41. The whole function of the brain is summed up in: error-correction.
  42. Functionally, the behaviour is the brain.

    On the brain's secret

  43. The secret of the mammalian brain is that it has long and slavishly fashioned itself to its environment.
  44. To refer to the head-ganglion of Homo sapiens as "Man's brain" is to appeal to our lowest prejudices.
  45. Only the incorrigibly sentimental speak of "Man's brain". Those who wish to stay clean-headed speak of the "head ganglion of Homo sapiens".

  56. No system is brain-like — every system is brain-like — as you please.

    On the "brain-like" control mechanism

  57. A mechanism is "brain-like" so far as it is effective: there is nothing more.

  63. There is no memory in the present — only a state of affairs.

    On Localisation of Memory

  64. Any system that stores its memories away from the site of action must do much work in remembering where it has put that memory.

    On the mystery of the brain

  65. "But that", said Mr Hick contemptuously, "can't be the explanation — there's no mystery in it."

  66. The machine that can produce all trajectories has no laws.
  67. The product set has no constraints.

    On Brain processes

  70. Natural selection insists that the nature of the parts shall be irrelevant for the behavior.
  71. No mammal will ever understand the mammalian brain completely.
  72. The man who talks today of probability in the brain is usually trying to return to the days when everything in the brain was so delightfully vague.
  73. The neurone is the one unit that, in psychology, is quite devoid of interest, it is too small to be visible in the man's action, and too large to be sufficient in memory.
  74. The neurone is the one unit that, in behaviour, is quite devoid of interest today; it is too small to be noticeable in a man's action, and too gross to carry a trace of memory.

    On Creativity

  83. The scientist does not believe in events without causes, not even when they happen in the brain.
  84. Introspection is the output of the verbalising mechanism.

    On Introspection

  85. That homo has a brain no more entitles him to assume he knows how he thinks than possession of a liver entitles him to assume that he knows how he metabolises.
  86. A man no more knows how he thinks, just because he has a brain in his skull, than he knows how he makes blood, because he has marrow in his bones.

    On Altruism

  94. "Help one another" is the selfishness of the species.

  130. Today's digital computer is organized like an army of a million men that can only get two into action at a time.
  131. The digital computer of today is like a centipede with a million legs, each of which can go forward in a microsecond; but as it can move only one pair at a time the whole animal is easily outrun by the tortoise.
