Hi. Remember that post three ages of men ago about five semi-obscure works by Tolkien that are really cool? They were: 
1. The Tolkien Reader
2. Smith of Wooton Major
3. Letters from Father Christmas
4. Mythopoeia
5. The Fall of Arthur
(Here is a link to that post, where I go into depth about 
The Tolkien Reader: http://woodbtwntheworlds.blogspot.com/2014/05/5-works-by-tolkien-you-may-not-have.html).
Anyway, I'd like to talk about another of the works on that list. This is the poem "Mythopoeia."
"Mythopoeia" (I spelled it right twice now, I should win something) was the product of an argument between Tolkien and his friend C.S. Lewis. Lewis argued that myths were ultimately "worthless" because they weren't true, but Tolkien argued that myths were valuable in their own right. Apparently he didn't manage to convince Lewis in conversation, but he went home and wrote a poem about it, which he dedicated to Lewis and then showed to him. The poem must have done the trick; it reportedly convinced Lewis that myths had value and weren't just a pack of worthless lies. The moral we learn from this little story is that, if in prose you don't succeed, try, try a poem. "Mythopoeia" also functions as a great defense of fantasy literature, especially taken along with Tolkien's essay "On Fairy Stories," which you can find in 
The Tolkien Reader.
Because "Mythopoeia" can be difficult to come across, I've reproduced it below, taken from this 
website. When you're done, you might want to listen to 
this analysis of the poem by Dr. Corey Olsen - but all, of course, at your own choosing.
To one who    said that myths were lies and therefore worthless,
even    though "breathed through silver"
PHILOMYTHUS    TO MISOMYTHUS 
You look at trees and label    them just so,
(for trees are `trees', and    growing is `to grow');
you walk the earth and    tread with solemn pace
one of the many minor    globes of Space:
a star's a star, some    matter in a ball
compelled to courses    mathematical
amid the    regimented, cold, Inane,
where destined atoms are    each moment slain.
At bidding of a Will, to    which we bend
(and    must), but only dimly apprehend,
great processes march on,    as Time unrolls
from dark beginnings to    uncertain goals;
and as on page o'erwitten    without clue,
with script and limning    packed of various hue,
and endless multitude of    forms appear,
some grim, some frail, some    beautiful, some queer,
each alien, except as kin    from one
remote Origo, gnat, man,    stone, and sun.
God made the petreous rocks,    the arboreal trees,
tellurian earth, and    stellar stars, and these
homuncular men, who walk    upon the ground
with nerves that tingle    touched by light and sound.
The movements of the sea,    the wind in boughs,
green grass, the large slow    oddity of cows,
thunder and lightning,    birds that wheel and cry,
slime crawling up from mud    to live and die,
these each are duly    registered and print
the brain's contortions    with a separate dint.
Yet trees and not `trees',    until so named and seen -
and never were so named,    till those had been
who speech's involuted    breath unfurled,
faint echo and dim picture    of the world,
but neither record nor a    photograph,
being divination, judgement,    and a laugh,
response of those that felt    astir within
by deep monition movements    that were kin
to life and death of trees,    of beasts, of stars:
free captives undermining    shadowy bars,
digging the foreknown from    experience
and panning the vein of    spirit out of sense.
Great powers they slowly    brought out of themselves,
and looking backward they    beheld the Elves
that wrought on cunning    forges in the mind,
and light and dark on    secret looms entwined.
He sees no stars who does    not see them first
of living silver made that    sudden burst
to flame like flowers    beneath the ancient song,
whose very echo after-music    long
has since pursued. There is    no firmament,
only a void, unless a    jewelled tent
myth-woven and    elf-patterned; and no earth,
unless the mother's womb    whence all have birth.
The heart of man is not    compound of lies,
but draws some wisdom from    the only Wise,
and still recalls him.    Though now long estranged,
man is not wholly lost nor    wholly changed.
Disgraced he may be, yet is    not dethroned,
and keeps the rags of    lordship one he owned,
his world-dominion by    creative act:
not his to worship the    great Artefact,
man,    sub-creator, the    refracted light
through whom is splintered    from a single White
to many hues, and endlessly    combined
in living shapes that move    from mind to mind.
Though all the crannies of    the world we filled
with elves and goblins,    though we dared to build
gods and their houses out    of dark and light,
and sow the seed of dragons,    'twas our right
(used or misused). The    right has not decayed.
We make still by the law in    which we're made.
Yes!    `wish-fulfilment dreams' we spin to cheat
our timid hearts and ugly    Fact defeat!
Whence came the wish, and    whence the power to dream,
or some things fair and    others ugly deem ?
All wishes are not idle,    not in vain
fulfilment we devise - for    pain is pain,
not for itself to be    desired, but ill;
or else to strive or to    subdue the will
alike were graceless; and    of Evil this
alone is dreadly certain:    Evil is.
Blessed are the timid    hearts that evil hate,
that quail in its shadow,    and yet shut the gate;
that seek no parley, and in    guarded room,
through small and bare,    upon a clumsy loom
weave rissues gilded by the    far-off day
hoped and believed in under    Shadow's sway.
Blessed are the men of    Noah's race that build
their little arks, though    frail and poorly filled,
and steer through winds    contrary towards a wraith,
a rumour of a harbour    guessed by faith.
Blessed are the    legend-makers with their rhyme
of things nor found within    record time.
It is not they that have    forgot the Night,
or bid us flee to organised    delight,
in lotus-isles of economic    bliss
forswearing souls to gain a    Circe-kiss
(and counterfeit at    that, machine-produced,
bogus seduction of the    twice-seduced).
Such isles they saw afar,    and ones more fair,
and those that hear them    yet may yet beware.
They have seen Death and    ultimate defeat,
and yet they would not in    despair retreat,
but oft to victory have    turned the lyre
and kindled hearts with    legendary fire,
illuminating Now and dark    Hath-been
with light of suns as yet    by no man seen.
I would that I might with    the minstrels sing
and stir the unseen with a    throbbing string.
I would be with the    mariners of the deep
that cut their slender    planks on mountains steep
and voyage upon a vague and    wandering quest,
for some have passed beyond    the fabled West.
I would with the    beleaguered fools be told,
that keep an inner fastness    where their gold,
impure and scanty, yet they    loyally bring
to mint in image blurred of    distant king,
or in fantastic banners    weave the sheen
heraldic emblems of a lord    unseen.
I will not walk with your    progressive apes,
erect and sapient. Before    them gapes
the dark abyss to which    their progress tends -
if by God's mercy progress    ever ends,
and does not ceaselessly    revolve the same
unfruitful course with    changing of a name.
I will not treat your dusty    path and flat,
denoting this and that by    this and that,
your world immutable    wherein no part
the little maker has with    maker's art.
I bow not yet before the    Iron Crown,
nor cast my own small    golden sceptre down.
In Paradise perchance the    eye may stray
from gazing upon    everlasting Day
to see the day-illumined,    and renew
from mirrored truth the    likeness of the True.
Then looking on the Blessed    Land 'twill see
that all is as it is, and    yet may free:
Salvation changes not, nor    yet destroys,
garden not gardener,    children not their toys.
Evil it will not see, for    evil lies
not in God's picture but in    crooked eyes,
not in the source but in    the tuneless voice.
In Paradise they look no    more awry;
and though they make anew,    they make no lie.
Be sure they still will    make, not been dead,
and poets shall have flames    upon their head,
and harps whereon their    faultless fingers fall:
there each shall choose for    ever from the All. 
There you have it: Tolkien's "Mythopoeia." Are you convinced?
