Reference excerpt

Matti Johannes Häyry (Finnish pronunciation: [ˈmɑtːi ˈhæy̯ry]; born 20 September 1956) is a Finnish philosopher. He teaches courses on Business Ethics and the Philosophy of Social Science at Aalto University. Häyry specialises in moral and political philosophy, and bioethics.

Education Häyry began his education at the National Defence University, Finland, where he earned a Commissioned Officer's Degree and Certificate between 1976 and 1979. Subsequently, he attended the University of Helsinki, obtaining a Bachelor of Arts in 1983, followed by a Master of Social Science in 1984. Continuing his academic advancement, he achieved a Licentiate in Social Science in 1987 and a Master of Arts from the Department of Philosophy in 1990. In 1991, he was awarded a Doctor of Social Science degree from the same university.

Career Matti Häyry's career spans several decades and includes positions in academia and research. He began his professional journey in the Finnish Defence Forces, serving as a Commissioned Officer in Signals and Communication from 1979 to 1981. Following this, he transitioned to academia, working as a Lecturer and Research Fellow in Practical and Theoretical Philosophy at the University of Helsinki from 1985 to 1995. He then served as Acting Professor of Practical Philosophy at the same university from 1995 to 1996. Between 1997 and 2000, he was an Academy Research Fellow at the Academy of Finland and the University of Helsinki. Subsequently, he became a Professor of Philosophy at the University of Kuopio from 1999 to 2002. From 2001 to 2004, in the United Kingdom, he served as a Professor of Moral Philosophy and Head of the Centre for Professional Ethics at the University of Central Lancashire in Preston. In 2004, he joined the University of Manchester, where he worked as a Professor of Bioethics and Philosophy of Law until 2013. During this time, he also held a Professorial Fellowship at the Collegium for Advanced Studies at the University of Helsinki from 2009 to 2011. In 2013, he returned to Finland, joining the Aalto University School of Business in Helsinki as a Professor of Philosophy of Management, a position he held until 2024. Currently, he is a Professor and Senior Fellow at Aalto University in Espoo. In an endeavour to express ethical ideas in an artistic format, Häyry produced in 2013 – with Tuija Takala, Corky Laing, and Lasse Väyrynen – a concept album on the ethics of genetics, Playing God—The Rock Opera. Häyry is a founding member of the International Association of Bioethics and he served on its board of directors from 2001 to 2009, and from 2007 to 2009 as the association's president.

Philosophy Häyry's main fields of interest have been moral and political philosophy and bioethics. His practical topics in bioethics have ranged from abortion, euthanasia, and resource allocation to genetics, systems biology, and synthetic biology. Theoretically, his work has centred on the main normative doctrines of European moral and political philosophy. Häyry is an antinatalist. He has participated in various podcasts and written a few papers on the subject.

Notes

Worked examples

Example 1 — a first encounter with Matti Häyry

Start with the simplest possible case. Write down what Matti Häyry claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Matti Häyry before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Matti Häyry ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Matti Häyry

In research
Matti Häyry appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Matti Häyry in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Matti Häyry is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 20th-century Finnish male writers, 20th-century Finnish philosophers, so understanding it makes those chapters shorter.
In everyday life
Look for Matti Häyry outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
