To acquire knowledge is neccessary at all times.
Jafar ibn Muhammad as-S
One way of looking at poetic periods is to notice what contemporary interests and knowledge penetrate the best verse written at the time and what moods are permitted in treating of these matters.
Kenneth Allott
If there is some end of the things we do, which we desire for its own sake, clearly this must be the good. Will not knowledge of it, then, have a great influence on life? Shall we not, like archers who have a mark to aim at, be more likely to hit upon what we should? If so, we must try, in outline at least, to determine what it is.
Aristotle
It is not easy to determine the nature of music, or why anyone should have a knowledge of it.
Aristotle
Not more knowledge but better use of the knowledge which we now have, is perhaps the main educational need and the main educational problem which confronts us.
Sir Norman Angell
Two signs of learned person are: acceptance of other people's criticism, and being knowledgeable about the angles and dimensions of rhetoric and debate.
Husayn ibn Al
To wisdom belongs the intellectual apprehension of things eternal; to knowledge, the rational apprehension of things temporal.
St. Augustine of Hippo
No one has yet been found so firm of mind and purpose as resolutely to compel himself to sweep away all theories and common notions, and to apply the understanding, thus made fair and even, to a fresh examination of particulars. Thus it happens that human knowledge, as we have it, is a mere medley and ill-digested mass, made up of much credulity and much accident, and also of the childish notions which we at first imbibed.
Francis Bacon
Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.
Francis Bacon
There are no incurable diseases only the lack of will. There are no worthless herbs only the lack of knowledge.
Avicenna
Knowledge is indivisible. When people grow wise in one direction, they are sure to make it easier for themselves to grow wise in other directions as well. On the other hand, when they split up knowledge, concentrate on their own field, and scorn and ignore other fields, they grow less wise even in their own field.
Isaac Asimov
The passionate controversies of one era are viewed as sterile preoccupations by another, for knowledge alters what we seek as well as what we find.
Freda Adler
Knowledge is a fine thing, and mother Eve thought so; but she smarted so severly for hers, that most of her daughters have been afraid of it since.
Abigail Adams
Even a little knowledge of Islam will show that its religion is not only tolerant of other Faiths, but most respectful, and indeed, fully accepts the divine inspiration of all theistic Faiths that came before Islam.
Aga Khan III
