The third of this kind of principles is : matter neither originates nor perishes; all the changes in the world concern form only; a postulate which on the recommendation of common sense has spread through all philosophical schools, not because it is to be taken as having been found so, or as having been demonstrated by arguments a priori, but because if we were to admit that matter itself is fleeting and transitory, nothing at all that is stable and lasting would be left any longer to serve for the explication of phenomena according to universal and perpetual laws, and hence nothing at all would be left for the exercise of the intellect.

Comprehension is neither an arbitrary act nor a passive experience, but a responsible act claiming universal validity. Such knowing is indeed objective in the sense of establishing contact with a hidden reality; a contact that is defined as the condition for anticipating an indeterminate range of yet unknown (and perhaps yet inconceivable) true implications. It seems reasonable to describe this fusion of the personal and the objective as Personal Knowledge. Personal knowledge is an intellectual commitment, and as such inherently hazardous. Only affirmations that could be false can be said to convey objective knowledge of this kind.
Michael Polanyi
Do not let us imagine that discoveries in the world of the higher mathematics, of physics or biology are going to remove or even reduce our difficulties on the moral plane...The realm of morals is a world neither of quantity nor of chemical action. It is a world of values. It is precisely these values of right and wrong, of good and evil, of honesty and courage, which matter supremely for religion and national life...I am not despising science. I am only suggesting that moral values, eternal in their quality, transient in their form and application, are the foundation of a country's greatness. If moral values flourish in our common life all will be well with the nation.
Stanley Baldwin
In America, the President reigns for four years, and journalism governs for ever and ever. Fortunately, in America journalism has carried its authority to the grossest and most brutal extreme. As a natural consequence it has begun to create a spirit of revolt, people are amused by it, or disgusted by it, according to their temperaments. but it is no longer the real force it was. It is not seriously treated. In England, journalism, except in a few well-known instances, not having been carried to such excesses of brutality, is still a great factor, a remarkable power. The tyranny that it proposes to exercise over people's private lives seems to me to be quite extraordinary.
Oscar Wilde
Whatever moral rules you have deliberately proposed to yourself abide by them as they were laws, and as if you would be guilty of impiety by violating any of them. Don't regard what anyone says of you, for this, after all, is no concern of yours. How long, then, will you put off thinking yourself worthy of the highest improvements and follow the distinctions of reason? You have received the philosophical theorems, with which you ought to be familiar, and you have been familiar with them. What other master, then, do you wait for, to throw upon that the delay of reforming yourself?... Let whatever appears to be the best be to you an inviolable law.
Epictetus
Marxist philosophy holds that the law of the unity of opposites is the fundamental law of the universe. This law operates universally, whether in the natural world, in human society, or in man's thinking. Between the opposites in a contradiction there is at once unity and struggle, and it is this that impels things to move and change. Contradictions exist everywhere, but they differ in accordance with the different nature of different things. In any given phenomenon or thing, the unity of opposites is conditional, temporary and transitory, and hence relative, whereas the struggle of opposites is absolute.
