Can we trust what we see?

Seek the truth.

Look beyond appearances, put doubt to work, discover the conditions and limits of knowledge.

Platonism

Plato

With Plato, question the gap between appearance and what makes something intelligible.

Rationalism

With Descartes, turn doubt into a method rather than a dead end.

Critical philosophy

With Kant, ask what makes experience possible and where our knowledge ends.

These connections are editorial suggestions: they bring differences into conversation without attributing a shared doctrine to these thinkers.
