Cicero: “It is even worse than refusing to set a man on his way: it is deliberately leading a man astray.”

Further than this, who fails to see that those promises are not binding which are extorted by intimidation or which we make when misled by false pretences?

For there are men who for fear of giving offence do not dare to express their honest opinion, no matter how excellent.

In my opinion, at least, we should always strive to secure a peace that shall not admit of guile.

For we are all attracted and drawn to a zeal for learning and knowing; and we think it glorious to excel therein, while we count it base and immoral to fall into error, to wander from the truth, to be ignorant, to be led astray.
