Beauty is truth, truth beauty – that is all
Ye know on earth, and all ye need to know.
– John Keats

Truth is expressed in and as beauty.
Aesthetics is very important,
If something is beautiful, it is true. If it is aesthetically ugly, the it must be wrong, untrue.

One cannot love truth if you cannot love beauty.
One cannot know truth without being sensitive to beauty.

Beauty is the way to truth, and the way and the goal are the same.
If you follow beauty you will be led into Truth.
The way is itself the goal.

And at the peak of experience they are one in the same
Beauty is Truth.
Truth is Beauty.
And that is all you know or need know in this world.
