To make astute people believe one is what one is not is, in most cases, harder than actually to become what one wishes to appear.

Truth only means something when it's hard to admit.

Knowing it — knowing it's true is one thing, but believing what you know... well, there's the tough part.

But when one believes in the reality of things, making them visible by artificial means is not quite the same as feeling that they are close at hand.

The more desire I have for something to work out a certain way, the less likely I am to see the truth.

It’s hard nowadays to get people to believe things. At least good things.

To make clever people believe we are what we are not is in most instances harder than really to become what we want to seem to be.

It is so hard to believe because it is so hard to obey.

What's real and what's true aren't necessarily the same.

The truth isn't easily pinned to a page. In the bathtub of history the truth is harder to hold than the soap and much more difficult to find.

you will know that it is a more difficult work to reject the opinion of others than to establish your own.

Many of you have already found out, and others will find out in the course of their lives, that truth eludes us if we do not concentrate our attention totally on it's pursuit. But even while it eludes us, the illusion of knowing it still lingers and leads to many misunderstandings. Also, truth seldom is pleasant; it is almost invariably bitter.

Truth is so hard to tell, it sometimes needs fiction to make it plausible.

If we take something to be the truth, we may cling to it so much that when the truth comes and knocks on our door, we won't want to let it in.
