Beauty is based on three conditions: Clearness, integrity and due
proportion.

Beauty exists in the practical knowledge of the tendencies affected by
the form in view of the object for which it is; in view, above all, of
the action which it exerts upon the beings with whom it is in relation.
Thus a thing is not only beautiful from the transparency of its
aptitudes, it is especially so from the beauty of the acts which its use
determines abroad. This is the reason why beauty is to all creatures an
object of appetency, of desire and of love.

Trinity.

There is a mystery full of deep instruction, a mystery whose divine
obscurities surpass all the light whose splendors dazzle us by their
supernatural clarity, and which, as a great saint once said, radiates
splendid beams and floods with the glory of its fires those spirits who
are blind with the blindness of holiness. This mystery, outside of which
all is to man dark and incomprehensible, illuminates everything and
explains it in the sense that it is the cause, the principle and the end
of all things.

This dazzling mystery is the universal criterion of all truth; it is the
science of sciences, which is self-defining and whose name is Trinity.

Here we foresee an objection to which we must first reply. Some will be
surprised that a system declared to be infallible should rest upon a
mystery; they will ask what a mystery can have to do with a purely
didactic question. Patience! You shall see that it cannot be otherwise.
Nothing is more evident than light, yet light is a mystery, the most
obscure of all mysteries. Thus light escapes the eye and it does not see
that by means of which it sees. Now, if light is a mystery, why should
not mystery be a light? Let us see first what the church teaches us in
regard to this mystery.

God is a word which serves as a pretext for every Utopia, for every
illusion and for every human folly. The Trinity is the express
refutation of all these stupidities; it is their remedy, corrective and
preservative. Deprive me of the Trinity and I can no longer understand
aught of God. All becomes dark and obscure to me, and I have no longer a
rational motive for hope.

The Trinity, the hypostatical basis of beings and things, is the
reflection of the Divine Majesty in its work. It is, as it were, a
reflection upon us of its own light. The Trinity is our guide in the
applied sciences of which it is at once the solution and the enigm
