What has not been examined impartially has not been well examined. Skepticism is therefore the first step towards truth.

Justice is the first virtue of those who command, and stops the complaints of those who obey.

A thing is not proved because no one has ever questioned it... Skepticism is the first step toward truth.

Scepticism is the first step towards truth.

Skepticism is the first step on the road to philosophy.
