When people have chosen a certain path, they should walk it with satisfaction and not try to make it appear as a tremendous sacrifice.David Bohm: On things as abstractions
January 2013, when asked whether she regretted choosing to return from Oxford to Burma, and her consequent imprisonment
The notion of a thing is thus seen to be an abstraction, in which it is conceptually separated from its infinite background and substructure. Actually, however, a thing does not and could not exist apart from the context from which has thus been conceptually abstracted. And therefore the world is not made by putting together the various “things” in it, but, rather, these things are only approximately what we find on analysis in certain contexts and under suitable conditions.David Bohm: On things becoming other kinds of thing
From The Essential David Bohm, edited by Lee Nichol, Routledge (2003), page 25. The text is part of an extract from Chapter 5 of D.Bohm, Causality and Chance in Modern Physics, University of Pennsylvania Press, Philadelphia (1957) and Routledge, London (1957).
If, however, we now start... from the notion of the qualitative infinity of nature, we are then immediately able to arrive at a type of definition of the mode of being of any given kind of thing that does not contradict the possibility of its becoming something else. For... no given thing can be exactly and in all respects the kind of thing that is defined by any specified conceptual abstraction. Instead, it is always something more than this and, at least in some respects, something different. Hence, if the thing becomes something else, no unresolvable contradiction is now necessarily implied. For it is in this case never exactly represented by our original concept of it.David Bohm: On science, perception and knowledge

The reason that we are proposing [for the similarity between science and the process of perception] is that scientific investigation is basically a mode of extending our perception of the world, and not mainly a mode of obtaining knowledge about it.David Bohm: On the mechanistic view of physics
From The Essential David Bohm, edited by Lee Nichol, Routledge (2003), page 66. The text is part of an extract from Appendix D of D.Bohm, The Special theory of Relativity, Routledge, London (,1996)
Physics has become almost totally committed to the notion that the order of the universe is basically mechanistic. The most common form of this notion is that the world is assumed to be constituted of a set of separately existent, indivisible and unchangeable “elementary particles,” which are the fundamental “building blocks” of the entire universe. Originally, these were thought to be atoms, but atoms were eventually divided into electrons, protons and neutrons. These later were thought to be the absolutely unchangeable and indivisible constituents of all matter, but then these were found to be the subject of transformation into hundreds of different kinds of unstable particles, and now even smaller particles called “quarks” and “partons” have been postulated to explain these transformations. Though these have not yet been isolated there appears to be an unshakable faith among physicists that either such particles, or some other kind yet to be discovered, will eventually make possible a complete and coherent explanation of everythingDavid Bohm: On the inseparability of fact and theory

...it has no meaning to separate the observed fact... from the theoretical notions of order that help to give “shape” to this fact...David Bohm: On Bohr‘s interpretation of de Broglie's pilot wave theory, during a discussion with Renée Weber
Fact and theory are thus seen to be different aspects of one whole in which analysis into separate but interacting parts is not relevant. That is to say, not only is undivided wholeness implied in the content of physics (notably relativity and quantum mechanics) but also in the manner of working in physics

Bohm: So the meaning of an experimental result and the form of the experimental conditions were no longer separate, they were a whole, as even Bohr said. This was immediately obvious in de Broglie’s interpretation whereas its a deep, impenetrable mystery in Bohr’s language.David Bohm: On ambiguity and context dependence in Niels Bohr’s interpretation of quantum mechanics
Weber: Did Bohr not accept it?
Bohm: Bohr did. Bohr had the insight to see this [unity], and this is the basis of his work on interpretation... [but he] has a very complex way of putting it which very few physicists understand. In fact... the only consistent interpretation of that kind is Bohr’s, and the number who understand it is very small. Most physicists are just using it, taking it for granted that Bohr has done it right.
From The Essential David Bohm, edited by Lee Nichol, Routledge (2003), page 142. The text is part of an extract from Chapter 2 of R.Weber, Dialogues with Scientists and Sages: The Search for Unity. Routledge and Kegan Paul (1986).
The text does not state what is meant by an “interpretation of that kind”, but it seems likely that it refers to interpretations (like Bohr’s) in which the wave function collapses when a measurement is made.
... Niels Bohr... has made one of the most consistent interpretations of the quantum theory given thus far. ...first we have to say that while the quantum theory contradicts the previously existent classical theory, it does not explain the theory’s basic concepts as an approximation or a simplification of itself, but it has to presuppose the classical concepts at the same time that it has to contradict them. The paradox is resolved in Bohr’s point of view by saying that the quantum theory introduces no new basic concepts at all. Rather what it does is to require that concepts such as position and momentum, which are in principle unambiguous in classical physics, must become ambiguous in quantum mechanics. But ambiguity is just a lack of well-defined meaning. So Bohr, at least tacitly, brings in the notion of meaning as crucial to the understanding of the content of the theory...David Bohm: On content, context, and meaning
[The] mathematics gives only statistical predictions. It not only fails to predict what will happen in a single measurement, it cannot even provide an unambiguous concept or picture of what sort of process is supposed to take place. So for Bohr the concepts are ambiguous, and the meaning of the concepts depends on the whole context of the experimental arrangement... on the large scale behaviour which was supposed to be explained by the particles themselves. So in some sense you do not have a “bottom level” but rather you find that, to a certain extent, the meaning of these particles has the same sort of ambiguity that we find in mental phenomena when we are looking at meaning.
Now I believe Bohr’s interpretation of quantum theory is consistent... but it is still not clear why matter should have this context dependence. He just says that quantum theory gives rise to it.

Content and context are two aspects that are inevitably present in any attempt to discuss the meaning of a given situation... this sort of context-dependence is just what is found in physics with regard to matter, as well as in considerations of mind or meaning.David Bohm: On nature and machines

I would say that the crucial difference between [nature] and a machine is that nature is infinite in its potential depths of subtlety and inwardness, while a machine is not. Although to a certain extent a machine such as a computer has something similar.Jacob Bronowski: On loss of commitment to reason in the West
From The Essential David Bohm, edited by Lee Nichol, Routledge (2003), page 172. The text is part of an extract from Chapter 3 of D Bohm, Unfolding Meaning: A Weekend of Dialogue, Routledge and Kegan Paul, London (,1987).
And I am infinitely saddened to find myself suddenly surrounded in the west by a sense of terrible loss of nerve, a retreat from knowledge into – into what? Into Zen Buddhism; into falsely profound questions about, Are we not really just animals at bottom; into extra-sensory perception and mystery. They do not lie along the line of what we are now able to know if we devote ourselves to it: an understanding of man himself. We are nature’s unique experiment to make the rational intelligence prove itself sounder than the reflex. Knowledge is our destiny. Self-knowledge, at last bringing together the experience of the arts and the explanations of science, waits ahead of us.Jacob Bronowski: At Auschwitz, on the consequences of a belief in absolute knowledge

In crafting the living world, selection has always acted on systems that exhibit spontaneous order. If I am right, this underlying order, further honed by selection, augurs a new place for us - expected, rather than vastly improbable, at home in the universe in a newly understood way.Frank Lambert: On Entropy
From the preface to 'At Home in the Universe'.
Entropy is not disorder. Entropy is not a measure of disorder or chaos. Entropy is not a driving force. Energy's diffusion, dissipation, or dispersion in a final state compared to an initial state is the driving force in chemistry. Entropy is the index of that dispersal within a system and between the system and its surroundingsPierre Simon Laplace: On God

Sir, I have no need of that hypothesis.Karl Popper: On the existence of physical reality
The central issue here is realism. That is to say, the reality of the physical world we live in: the fact that this world exists independently of ourselves; that it existed before life existed, acording to our best hypotheses; and that it will continue to exist, for all we know, long after we have all been swept away.Attributed to Eleanor Roosevelt
I have argued in favour of realism in various places. My arguments are partly rational, partly ad hominem, and partly even ethical. It seems to me that the attack on realism, although intellectually interesting and important, is quite unacceptable, especially after two world wars and the real suffering - avoidable suffering - that was wantonly produced by them; and that any argument against realism which is based on modern atomic theory - on quantum mechanics - ought to be silenced by the memory of the reality of the events of Hiroshima and Nagasaki. (I say this in full admiration for the modern atomic theory and quantum mechanics, and of the scientists who have worked and who are now working in this field.)

This was Urey's response when asked what he expected to get from the experiment his student, Stanley Miller, was conducting on pre-biotic chemical synthesis in a reducing atmosphere. He was referring to the one hundred plus volume compendium begun by Friedrich Beilstein, "Beilsteins Handbuch der Organische Chemie", which describes all the organic compounds that have been synthesised.

You can have a soup of anything.
During a conversation at the 'Conditions for the emergence of life' conference at the Royal Society in London in 2006, in which I outlined the SimSoup model, and mentioned that the name SimSoup was not intended to suggest only a soup of large molecules as in heterotrophic theories of the Origin of Life; it could also be used to model small molecule theories such as that of Prof. Wächtershäuser
