We must resist the seductive notion that others can be trusted to guide our consciences for us. We must remain true to our instincts and remember that something can still be completely wrong even if no one is protesting, even if other people are going along with it, even if we are told by those in authority that everything is 'just fine.' Listen to your instincts.
If your words don't reflect your knowledge, you don't teach others.
"The secret of freedom lies in educating people whereas the secret of tyranny is in keeping them ignorant" - Maximilien Robespierre
