O what their joy and their glory must be, Those
endless sabbaths the blessed ones see! -- Peter
Abelard, Hymnus Paraclitensis
Against the disease of writing one must take
special precautions, since it is a dangerous and
contagious disease. -- Peter Abelard, Letter 8,
Abelard to Heloise
Adams, Henry
B.
Morality is a private and costly luxury. --
Henry B. Adams, The Education of Henry
Adams
Adler,
Alfred
It is easier to fight for one's principles than
to live up to them. -- Alfred Adler, quoted in
Phyliss Bottome's Alfred Adler: Apostle of
Freedom
Adler, Mortimer
J.
The only standard we have for judging all of our
social, economic, and political institutions and
arrangements as just or unjust, as good or bad, as
better or worse, derives from our conception of the
good life for man on earth, and from our conviction
that, given certain external conditions, it is
possible for men to make good lives for themselves
by their own efforts. -- Mortimer J. Adler, The
Adler Archives
Man's greatness lies in his power of thought. --
Mortimer J. Adler, The Adler Archives
We acknowledge but one motive -- to follow the
truth as we know it, whithersoever it may lead us;
but in our heart of hearts we are well assured that
the truth which has made us free, will in the end
make us glad also. -- Mortimer Adler, The Adler
Archives
If philosophy did not exist, we would have no
moral philosophy as a branch of knowledge and we
would have no understanding of science itself, for
when scientists write about science, they do so as
philosophers, not as scientists. -- Mortimer Adler,
The Adler Archives
Aeschylus
It is always in season for old men to learn. --
Aeschylus, Agamemnon
Alexander,
Samuel
All the vital problems of philosophy depend for
their solutions on the solution of the problem what
Space and Time are and more particularly how they
are related to each other.
Al-Ghazali, Abu Hamid
Muhammad Ibn Muhammad
Man's nature is made up of four elements, which
produce in him four attributes, namely, the
beastly, the brutal, the satanic, and the divine.
In man there is something of the pig, the dog, the
devil, and the saint. -- Abu Hamid Muhammad Ibn
Muhammad Al-Ghazali (1058-1111), The Main
Problems of Abu Nasr Al-Paraba
Althusser,
Louis
Ideology...is indispensable in any society if
men are to be formed, transformed and equipped to
respond to the demands of their conditions of
existence. -- Louis Althusser, For Marx
Anselm,
St.
For I do not seek to understand that I may
believe, but I believe in order to understand. For
this I believe -- that unless I believe, I should
not understand. -- St. Anselm,
Proslogium
God is that, the greater than which cannot be
conceived. -- St. Anselm, Proslogion
Aquinas, St.
Thomas
Law: an ordinance of reason for the common good,
made by him who has care of the community. --
Thomas Aquinas, Summa Theologica
The human soul is on the boundary line of
corporeal and spiritual creatures, and therefore
the powers of each come together in it. -- Thomas
Aquinas, Summa Theologica
Justice gives to each man his due, neither more
nor less. -- Thomas Aquinas, Summa
Theologica
For a war to be just three conditions are
necessary -- public authority, just cause, right
motive. -- Thomas Aquinas, Summa
Theologica
Honour is not that reward of virtue, for which
the virtuous work, but they receive honour from men
by way of reward as from those who have nothing
greater to offer. But virtue's true reward is
happiness itself, for which the virtuous work,
whereas if they worked for honour, it would no
longer be virtue, but ambition. -- Thomas Aquinas,
Summa Theologica
Now among all passions inflicted from without,
death holds the first place, just as sexual
concupiscences are chief among internal passions.
Consequently, when a man conquers death and things
directed to death, his is a most perfect victory.
-- Thomas Aquinas, Summa Theologica
Reason in man is rather like God in the world.
-- Thomas Aquinas, Opusc. 11, 1 de Regno,
12
There is no case known (neither is it, indeed,
possible) in which a thing is found to be the
efficient cause of itself; for so it would be prior
to itself, which is impossible. -- Thomas Aquinas,
Summa Theologica
Man has free choice, or otherwise counsels,
exhortations, commands, prohibitions, rewards and
punishments would be in vain. If the will were
deprived of freedom...no praise would be given to
human virtue; since virtue would be of no account
if man acted not freely: there would be no justice
in rewarding or punishing, if man were not free in
acting well or ill: and there would be no prudence
in taking advice, which would be of no use if
things occurred of necessity...
Augustine,
Saint
The good man, although he is a slave, is free;
but the bad man, even if he reigns, is a slave, and
a slave not of just one man but, what is far more
grievous, of as many masters as he has vices. --
Saint Augustine, The City of God
The law of liberty is the law of love. -- Saint
Augustine, Letter 167
Thou madest us for Thyself and our heart is
restless until it rest in Thee [referring to
God]. -- Saint Augustine,
Confessions
Six is a number perfect in itself, and not
because God created the world in six days; rather
the contrary is true. God created the world in six
days because this number is perfect, and it would
remain perfect, even if the work of the six days
did not exist. -- Saint Augustine, The City of
God
For, as among the powers in man's society the
greater authority is obeyed in preference to the
lesser, so must God above all.
Averroes
Knowledge is the conformity of the object and
the intellect. -- Averroes, Destructio
Destructionum
Ayer,
A.J.
No morality can be founded on authority, even if
the authority were divine. -- A. J. Ayer, Essay
on Humanism
We...define a metaphysical sentence as a
sentence which purports to express a genuine
proposition, but does, in fact, express neither a
tautology nor an empirical hypothesis. And as
tautologies and empirical hypotheses form the
entire class of significiant propositions, we are
justified in concluding that all metaphysical
assertions are nonsensical. -- A.J. Ayer,
Language, Truth and Logic
If it came to the point where we had the means
of knowing what was going on in a person's brain
and could use this as a basis for predicting what
he would do, and if this knowlege extended to our
own future conduct, it is unlikely that our present
view of life would remain the same. -- A.J. Ayer,
The Concept of a Person
