Ideas that shift your perspective.

01

Distinguishing opinion from knowledge

An opinion can be true without its holder being able to give an account of it. The dialogues explore what makes knowledge secure: justification, intelligibility and its relationship to its object. This inquiry develops differently across the texts and does not always reach a settled definition.

A situation to think through

You may choose the right answer by chance. Understanding why it is right changes your ability to respond to a new situation.

02

Thinking about intelligible forms

In several dialogues, Plato distinguishes changing sensible things from intelligible objects such as Beauty or Justice. Forms are not merely perfect pictures: they belong to an inquiry into what makes something understandable. Their relationship to sensible things itself raises difficulties.

A situation to think through

Comparing several decisions called just requires asking what makes them just beyond their circumstances and your personal preferences.

03

Educating attention and desire

Learning is not simply accumulating information. In Republic, the image of the cave describes a difficult and sometimes painful turning of the gaze. Education involves habits, desires and the ability to return to conversation with those who do not yet see things in the same way.

A situation to think through

An encounter or a book may make a previously invisible injustice apparent. What must change in your habits so that you do more than merely glimpse it?

04

Questioning justice in soul and city

Republic connects political organisation with the subject’s inner conflicts. Justice is examined as a particular ordering of functions and desires. This demanding model is also contestable: the passage from order to political hierarchy needs discussion, without treating every kind of harmony as justice.

A situation to think through

An efficiently organised group is not necessarily equitable. Ask who decides, who benefits from the rules and who can challenge them.
