I never allow myself to have an opinion on anything unless I know the other side’s argument better than they do.

Never allow oneself to have an opinion on anything when you don't know the other side's arguments better than they do.

Never make a calculation until you know the answer.

Since we are not permitted to act, we are obliged to know.

I never allow myself to have an opinion on anything that I don't know the other side's argument better than they do.

You do not have a right to an opinion. You have the right to an informed opinion. You do not have a right to be ignorant.

One should never judge anything unless it is known.

It is no good any longer having any opinion upon anything...

if any opinion is compelled to silence, that opinion may, for aught we can certainly know, be true. To deny this is to assume our own infallibility.

We can never know anything.

This is something, eh, that is the kind of thing that must be gone through with what I believe is best not talked about too much until we know whatever answers there will be.

In all judgements by which we describe anything as beautiful, we allow no one to be of another opinion.

We cannot allow quibbles to stand in the way of the truth.

If we are open only to discoveries which will accord with what we know already, we may as well stay shut.
