Gaston Bachelard (French: baʃlaʁ; June 27, 1884 - October 16, 1962) was a French philosopher. He made contributions in the fields of poetics and the philosophy of science. To the latter he introduced the concepts of epistemological obstacle and epistemological break (obstacle épistémologique et rupture épistémologique). He rose to some of the most prestigious positions in the Académie française and influenced many subsequent French philosophers, among them Michel Foucault, Louis Althusser, Dominique Lecourt and Jacques Derrida.

Life and work:
Bachelard was a postmaster in Bar-sur-Aube, and then studied physics before finally becoming interested in philosophy. He was a professor at Dijon from 1930 to 1940 and then became the inaugural chair in history and philosophy of the sciences at the Sorbonne.
Bachelard's psychology of science:
Bachelard's studies of the history and philosophy of science in such works as Le nouvel esprit scientifique ("The New Scientific Spirit", 1934) and La formation de l'esprit scientifique ("The Formation of the Scientific Mind", 1938) were based on his vision of historical epistemology as a kind of psychoanalysis of the scientific mind, or rather of the psychological factors in the development of sciences. For instance, he takes the example of Heisenberg's first chapters of the Physical principles of the quantum theory, where he alternatively defends a corpuscular theory and an undulatory theory, correcting each by the others (The New Scientific Mind, IV). This, claims Bachelard, is an excellent example of the importance of psychological training in sciences, as one should correct spontaneous errors by taking the opposite stance.
In the English-speaking world, the connection Bachelard made between psychology and the history of science has been little understood. Bachelard demonstrated how the progress of science could be blocked by certain types of mental patterns, creating the concept of obstacle épistémologique ("epistemological obstacle"). One task of epistemology is to make clear the mental patterns at use in science, in order to help scientists overcome the obstacles to knowledge.
Epistemological breaks: the discontinuity of scientific progress:
Bachelard was critical of Auguste Comte's positivism, which considered science as a continual progress. To Bachelard, scientific developments such as Einstein's theory of relativity demonstrated the discontinuous nature of the history of sciences. Thus models that framed scientific development as continuous, such as that of Comte and Émile Meyerson, seemed simplistic and erroneous to Bachelard.
Through his concept of "epistemological break", Bachelard underlined the discontinuity at work in the history of sciences. However the term "epistemological break" itself is almost never used by Bachelard, but became famous through Louis Althusser.
He showed that new theories integrated old theories in new paradigms, changing the sense of concepts (for instance, the concept of mass, used by Newton and Einstein in two different senses). Thus, non-Euclidean geometry did not contradict Euclidean geometry, but integrated it into a larger framework.
The role of epistemology in science:
Bachelard was a rationalist in the Cartesian sense, although he recommended his "non-Cartesian epistemology" as a replacement for the more standard Cartesian epistemology. He compared "scientific knowledge" to ordinary knowledge in the way we deal with it, and saw error as only illusion: "Scientifically, we think of truth as the historical rectification of a long error, and we think of experience as the rectification of the common and original illusion (illusion première).
The role of epistemology is to show the history of the (scientific) production of concepts; those concepts are not just theoretical propositions: they are simultaneously abstract and concrete, pervading technical and pedagogical activity. This explains why "The electric lightbulb is an object of scientific thought... an example of an abstract-concrete object." To understand the way it works, one has to take the detour of scientific knowledge. Epistemology is thus not a general philosophy that aims at justifying scientific reasoning. Instead it produces regional histories of science.
Shifts in scientific perspective:
Bachelard saw how seemingly irrational theories often simply represented a drastic shift in scientific perspective. For instance, he claimed that the theory of probabilities was just another way of complexifying reality through a deepening of rationality (even though critics like Lord Kelvin found this theory irrational).
One of his main theses in The New Scientific Mind was that modern sciences had replaced the classical ontology of the substance with an "ontology of relations", which could be assimilated to something like a process philosophy. For instance, the physical concepts of matter and rays correspond, according to him, to the metaphysical concepts of the thing and of movement; but whereas classical philosophy considered both as distinct, and the thing as ontologically real, modern science can not distinguish matter from rays: it is thus impossible to examine an immobile thing, which was precisely the condition for knowledge according to classical theory of knowledge (Becoming being impossible to be known, in accordance with Aristotle and Plato's theories of knowledge).
In non-Cartesian epistemology, there is no "simple substance" as in Cartesianism, but only complex objects built by theories and experiments, and continuously improved (VI, 4). Intuition is therefore not primitive, but built (VI, 2). These themes led Bachelard to support a sort of constructivist epistemology.
Other academic interests:
In addition to epistemology, Bachelard's work deals with many other topics, including poetry, dreams, psychoanalysis, and the imagination. The Psychoanalysis of Fire (1938) and The Poetics of Space (1958) are among the most popular of his works. Sartre cites the former and Bachelard's "Water and Dreams" in his Being and Nothingness.
Thomas S. Kuhn used Bachelard's notion of "epistemological rupture" (coupure or rupture épistémologique) as re-interpreted by Alexandre Koyré to develop his theory of paradigm changes; Althusser, Georges Canguilhem (his successor at the Sorbonne) and Michel Foucault also drew upon Bachelard's epistemology.
Bachelard's daughter, Suzanne, translated Husserl's Formale und transzendentale Logik into French.
Et, quoi qu'on en dise, dans la vie scientifique, les problèmes ne se posent pas d'eux-mêmes. C'est précisément ce sens du problème qui donne la marque du véritable esprit scientifique. Pour un esprit scientifique, toute connaissance est une réponse à une question. S'il n'y a pas eu de question, il ne peut y avoir de connaissance scientifique. Rien ne va de soi. Rien n'est donné. Tout est construit -- Gaston Bachelard (La formation de l'esprit scientifique, 1934),
"And, irrespective of what one might assume, in the life of a science, problems do not arise by themselves. It is precisely this that marks out a problem as being of the true scientific spirit: all knowledge is in response to a question. If there were no question, there would be no scientific knowledge. Nothing proceeds from itself. Nothing is given. All is constructed."
It is the pen which dreams. (The Poetics of Reverie, 1960),
It is not a question of observation which propels mankind forward as if toward a looking glass of great magnitude; it is an instance of aggrandized reflection that insinuates the human psyche to the inhuman.,
