Biography

Origin He was born as the son of Stanisław Hartman, a mathematics professor, and a great-great-grandson of rabbi Izaak Kramsztyk.

Early life and education Hartman graduated from the Catholic University of Lublin in 1990. He received doctorate from the Jagiellonian University in 1995, upon dissertation Problematyka heurystyki filozoficznej supervised by Władysław Stróżewski.

Professional work In 1994, Hartman was appointed an assistant professor at the Institute of Philosophy at the Jagiellonian University, then in 1995 an associate professor in the Department of Philosophy and Bioethics at the Jagiellonian University Medical College. In 2003 he became the head of the department, and in 2008 was appointed Full Professor of Humane Sciences. Between 2013 and 2014, he was a member of Polish national ethics committee (Komisja do spraw etyki w ochronie zdrowia). In his philosophical work Hartman focuses on ethics and bioethics, his scientific interests also include especially metaphilosophy and political philosophy. Hartman is also known as a left-winged publicist, he's been publishing in magazines such as Gazeta Wyborcza, Tygodnik Powszechny, Dziennik Gazeta Prawna, Rzeczpospolita, Polityka, Newsweek Polska and Przekrój. In 2009 he was awarded with Grand Press for the best publicist. He is active in the politics. In 2011 Polish parliamentary election he was a candidate for the MP of Democratic Left Alliance. He received 2209 votes and didn't manage to get to the parliament. Hartman had been a member of the anti-clerical Your Movement party from its inception in October 2013 to September 2014, having been considered one its key members. 2014 proved to be very onerous for the party when it received mere 3.6% of the votes in the elections to the European Parliament of 2014, lagging far behind its rivalry Democratic of the Left Alliance. The precarious voting results threatened the very existence of the party when many of its members quit. Despite proving his loyalty, Hartman soon lost his membership after publishing on his blog an article regarding recent debates on the legality of incest in Germany (by the Deutscher Ethikrat) and proposing to open a discussion on this topic in Poland. The public opinion was outraged and went as far as to accuse him of espousing incest, which he denied. Soon, a voting inside the party was held and Hartman was expelled, having lost 7 to 1. Hartman condemned the decision, criticising it as "curtailing freedom of speech in a party whose main precept was in fact freedom".

Family In 1989 Jan Hartman married Barbara, a sociologist. Their daughter, Zofia, was born in 1998.

Worked examples

Example 1 — a first encounter with Jan Hartman (philosopher)

Start with the simplest possible case. Write down what Jan Hartman (philosopher) 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 Jan Hartman (philosopher) 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 Jan Hartman (philosopher) 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 Jan Hartman (philosopher)

In research: Jan Hartman (philosopher) 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 Jan Hartman (philosopher) 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: Jan Hartman (philosopher) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 births, 20th-century Polish Jews, 21st-century Polish Jews, so understanding it makes those chapters shorter.
In everyday life: Look for Jan Hartman (philosopher) 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.
