Factual truth:
Arendt tells us in Truth and Politics
For Aristotle and many others, the key question is:
How should we live together in communities? How should we organize our communities?
Three answers
Essay on “Science as a Vocation” ultimately takes up the question of “what is the value of science?”
Answer 1:
instrumental rationality: the alignment of our actions such that they attain our desired ends.
Science can inform us about the condition and behavior of people and things in our social and natural environment. Thus we can make better decisions about the actions we choose
Aligning the means (what we do) with the ends (what we intend to achieve)
Answer 2: clarity
Science/truth can clarify: Are there unexpected consequences that place our values in conflict? What trade-offs do we have to make between the ends we desire.
Science/truth reveals inconvenient facts, where the world forces us to re-evaluate our value commitments.

Rainer Forst makes an argument drawing on Kant that pursuit of truth is essential for Freedom.
Forst takes a conception of freedom as autonomy:
power:
is the capacity of (person) A to motivate (person) B to think or do something that B would otherwise not have thought or done.
Forst argues that power always gives reasons (justifications) to motivate action.
reasons:

power can be compatible with freedom when we are given good reasons.
power becomes domination:
when the power of A rests on either the threat of violence, controlling the information that B has, or denying B the opportunity to question or challenge the reasons given by A.
That is, either the reasons given are poor or the process of giving reasons is flawed
when reasons are “coercive”: bodily, material, emotional threats
when reasons given to show there is “a problem” to be fixed are false or exclude other “problems” we might consider fixing:
when the proposed actions are known to not solve the “problem”
when reasons/our compliance with power depends on naturalizing something that is not natural
when we are denied participation in questioning/challenging reasons
Are these “good” reasons?
Where does truth come in?
In order for us to accept reasons as “good” and to change our minds or behaviors without domination… we must have access to truths about the world.
Arendt ponders the phrase “Let justice be done though the world may perish”
Arendt is concerned with factual truth:
Contrast this with rational truth, such as mathematical theorems or laws of physics:
the details of rational truths are irrelevant to most politics (unless you’re Galileo)
For Arendt, the opposite of factual truth is lying.
It is most dangerous when it is organized lying
If we think everything is a lie, does the idea of truth matter?
