Thomas Kuhn

"The young scientist has an advantage: fewer paradigms to unlearn."

"What appears as simple facts are actually interpretations laden with theory."

"The practice of science is deeply embedded in its historical context."

"Seeing is not a passive act; it is always interpretive and theoretical."

"Scientists resist paradigm change not from stupidity, but from rationality."

"The instruments we invent shape the nature we discover."

"Language carries within it the assumptions of those who created it."

"Crisis in science is not a sign of failure, but a prerequisite for progress."

"What we call facts are actually the products of scientific activity."

"The scientific community is a human community, subject to all human limitations."

"Revolutions in science often seem irrational to those outside them."

"The puzzle-solving phase of science is often boring to non-scientists."

"Our perceptions are shaped by the questions we bring to nature."

"The past looks different when viewed through a new paradigm."

"Scientists live in two worlds: the world of instruments and the world of concepts."

"What counts as a good explanation depends on your paradigm."

"The development of science is not a linear ascent toward truth."

"Anomalies are not threats; they are opportunities for growth."

"The scientist who ignores anomalies is practicing normal science."

"Communities of scientists are bound by invisible ties of shared understanding."

"To understand a paradigm, you must enter into its world of assumptions."

"The history of science is littered with 'obvious' truths that were dead wrong."

"Science is not about discovering what is; it is about constructing what we find useful."

"Paradigms are not chosen by logic alone; they are adopted by conviction."

"The scientist's eye is trained by years of practice with exemplars."

"What seems clear to us is clear only because of our particular position in history."

"Revolutionary change in science resembles a conversion experience."

"The evidence never speaks for itself; it is always interpreted by theory."

"Science progresses through cycles of normal science and revolutionary crisis."

"The future history of science will reinterpret our current certainties."
