History of philosophy Quotes

“Italy is full of historical buildings. And Europe holds a great history of philosophy from Greece until today. I read all those books and see these buildings, and I think of where I stand when I design my architecture.”

“I keep finding myself confronted with the question, “What is the aim of man’s life?” and, no matter what result my reflections reach, no matter what I take to be life’s source, I invariably arrive at the conclusion that the purpose of our human existence is to afford a maximum of help towards the universal development of everything that exists.If I meditate as I contemplate nature, I perceive everything in nature to be in constant process of development, and each of nature’s constituent portions to be unconsciously contributing towards the development of others. But man is, though a like portion of nature, a portion gifted with consciousness, and therefore bound, like the other portions, to make conscious use of his spiritual faculties in striving for the development of everything existent.If I meditate as I contemplate history, I perceive the whole human race to be for ever aspiring towards the same end.If I meditate on reason, if I pass in review man’s spiritual faculties, I find the soul of every man to have in it the same unconscious aspiration, the same imperative demand of the spirit.If I meditate with an eye upon the history of philosophy, I find everywhere, and always, men to have arrived at the conclusion that the aim of human life is the universal development of humanity.If I meditate with an eye upon theology, I find almost every nation to be cognizant of a perfect existence towards which it is the aim of mankind to aspire.So I too shall be safe in taking for the aim of my existence a conscious striving for the universal development of everything existent. I should be the unhappiest of mortals if I could not find a purpose for my life, and a purpose at once universal and useful… Wherefore henceforth all my life must be a constant, active striving for that one purpose.”

“In fact the problem Leopardi is facing is speculative and metaphysical, a problem in the history of philosophy from Parmenides to Descartes and Kant: the relationship between the idea of infinity as absolute space and absolute time, and our empirical knowledge of space and time.”

“The analytical geometry of Descartes and the calculus of Newton and Leibniz have expanded into the marvelous mathematical method—more daring than anything that the history of philosophy records—of Lobachevsky and Riemann, Gauss and Sylvester. Indeed, mathematics, the indispensable tool of the sciences, defying the senses to follow its splendid flights, is demonstrating today, as it never has been demonstrated before, the supremacy of the pure reason.”

“Our conduct of the ontological investigation in the first and second parts opens up for us at the same time a view of the way in which these phenomenological investigations proceed. This raises the question of the character of method in ontology. Thus we come to the third part of the course: the scientific method of ontology and the idea of phenomenology. The method of ontology, that is, of philosophy in general, is distinguished by the fact that ontology has nothing in common with any method of any of the other sciences, all of which as positive sciences deal with beings. On the other hand, it is precisely the analysis of the truth-character of Being which shows that Being also is, as it were, based in a being, namely, in the Dasein. Being is given only if the understanding of Being, hence the Dasein, exists. This being accordingly lays claim to a distinctive priority in ontological inquiry. It makes itself manifest in all discussions of the basic problems of ontology and above all in the fundamental question of the meaning of Being in general. The elaboration of this question and its answer requires a general analytic of the Dasein. Ontology has for its fundamental discipline the analytic of the Dasein. This implies at the same time that ontology cannot be established in a purely ontological manner. Its possibility is referred back to a being, that is, to something ontical―the Dasein. Ontology has an ontical foundation, a fact which is manifest over and over again in the history of philosophy down to the present. For example, it is expressed as early as Aristotle's dictum that the first science, the science of Being, is theology. As the work of the freedom of the human Dasein, the possibilities and destinies of philosophy are bound up with man's existence, and thus with temporality and with historicality, and indeed in a more original sense than is any other science. Consequently, in clarifying the scientific character of ontology, *the first task is the demonstration of its ontical foundation* and the characterisation of this foundation itself."―from_The Basic Problems of Phenomenology_”

“Plato's proposals in this matter are abhorrent to all true Christians. His intentions were, of course, excellent, for he desired the greatest possible improvement of the human race; but his good intentions led him to the proposal of measures which are necessarily unacceptable and repugnant to all those who adhere to Christian principles concerning the value of the human personality and the sanctity of human life. Moreover, it by no means follows that what has been found successful in the breeding of animals, will also prove successful when applied to the human race, for man has a rational soul which is not intrinsically dependent on matter but is directly created by Almighty God. Does a beautiful soul always go with a beautiful body or a good character with a strong body? Again, if such measures were successful — and what does "successful" mean in this connection? — in the case of the human race, it does not follow that the Government has the right to apply such measures. Those who to-day follow, or would like to follow, in the footsteps of Plato, advocating, e.g. compulsory sterilisation of the unfit, have not, be it remembered, Plato's excuse, that he lied at a period anterior to the presentation of the Christian ideals and principles. — 230”

“[O]ther thinkers have philosophised since the time of Plato, but that does not destroy the interest and beauty of his philosophy”
