Moral virtue can be without some of the intellectual virtues, namely, wisdom, science and art, but not without understanding and prudence. Moral virtue cannot be without prudence, because moral virtue is habit of choosing, that is, making us choose well.
The intellectual soul, because it can comprehend universals, has a power extending to the infinite; therefore it cannot be limited by nature either to certain fixed natural judgments, or to certain fixed means whether of defense or of clothing, as is the case with other animals, the souls of which have knowledge and power in regard to fixed particular things. Instead of all these, man has by nature his reason and his hands, which are the organs of organs, since by their means man can make for himself instruments of an infinite variety, and for any number of purposes.
There is no surer mark of the absence of the highest moral and intellectual qualities than a cold reception of excellence.
All that a man does outwardly is but the expression and completion of his inward thought. To work effectually, he must think clearly; to act nobly, he must think nobly. Intellectual force is a principal element of the soul’s life, and should be proposed by every man as the principal end of his being.
Courage is always greatest when blended with meekness; intellectual ability is most admirable when it sparkles in the setting of a modest self-distrust; and never does the human soul appear so strong as when it forgoes revenge and dares to forgive an injury.
Cruelty is perhaps the worst kind of sin. Intellectual cruelty is certainly the worst kind of cruelty.
We do not need more national development, we need more spiritual development. We do not need more intellectual power, we need more spiritual power. We do not need more knowledge, we need more character... We do not need more of the things that are seen, we need more of the things that are unseen.
Philosophers have very justly remarked that the only solid instruction is that which the pupil brings from his own depths; that the true instruction is not that which transmits notions wholly formed, but that which renders him capable of forming for himself good opinions. That which they have said in regard to the intellectual faculties applies equally to the moral faculties. There is for the soul a spontaneous culture, on which depends all the real progress in perfection.
Genuine intellectual integrity is found in experimental knowing. Until this lesson is fully learned, it is not safe to dissociate knowledge from experiment nor experiment from experience.
The dominant vocation of all human beings at all times is living - intellectual and moral growth.
To accept as a fact of life that a certain technology will be used for the simple reason that we know how to use it, or that we shall continue to live under a certain social system after it has become too complicated for human understanding, is tantamount to an abdication of intellectual and social responsibility.
It is a welcome symptom in an age which is commonly denounced as materialistic, that it makes heroes of men whose goals lie wholly in the intellectual and moral sphere. This proves that knowledge and justice are ranked above wealth and power by a large section of the human race.
Only those who know the supremacy of the intellectual life - the life which has a seed of ennobling thought and purpose within it - can understand the grief of one who falls from the serene activity into the absorbing soul wasting struggle.
When we have something for a long time we usually take it for granted. From the day we were born we have breathed air and seen sunlight and the beauty of nature. We have had sight, hearing, taste, smell, and touch for such a long time we have lost our appreciation for them. We take our daily pleasures and our intellectual attainments for granted.
Two principles govern the moral and intellectual world. One is perpetual progress, the other the necessary limitations to that progress. If the former alone prevailed, there would be nothing steadfast and durable on earth, and the whole of social life would be the sport of winds and waves. If the alter had exclusive sway, or even if it obtained a mischievous preponderancy, every thing would petrify or rot. The best ages of the world are those in which these two principles are the most equally balanced. In such ages every enlightened man ought to adopt both principles, and with one hand develop what he can, with the other restrain and uphold what he ought.
The sense of ultimate truth is the intellectual counterpart of the aesthetic sense of perfect beauty, or the moral sense of perfect good.
In the power of fixing the attention lies the most precious of the intellectual habits.
Our perceptions and our understanding are directed, in large measure, by our will. We are aware of, and we think about, the things which, for one reason or another, we want to see and understand. Where there’s a will there is always an intellectual way. The capacities of the human mind are almost indefinitely great.
Mankind have a great aversion to intellectual labor, but, even supposing knowledge to be easily attainable, more people would be content to be ignorant than would take even a little trouble to acquire it.
The highest perfection of intellectual nature lies in a careful and constant pursuit of true and solid happiness; so the care of ourselves that we mistake not imaginary for real happiness, is the necessary foundation of our liberty.
