The natural philosopher, in addition to the sensations common to all men inspired by the event of death, believes that he sees with more certainty that it is attended with the annihilation of sentiment and thought. He observes the mental powers increase and fade with those of the body, and even accommodate themselves to the most transitory changes of our physical nature. Sleep suspends many of the faculties of the vital and intellectual principle; drunkenness and disease will either temporarily or permanently derange them. Madness or idiotcy may utterly extinguish the most excellent and delicate of those powers. In old age the mind gradually withers; and as it grew and was strengthened with the body, so does it together with the body sink into decrepitude. Assuredly these are convincing evidences that so soon as the organs of the body are subjected to the laws of inanimate matter, sensation, and perception, and apprehension are at an end.

Mathematics have a triple aim. They must furnish an instrument for the study of nature. But that is not all: they have a philosophic aim and, I dare maintain, an esthetic aim. They must aid the philosopher to fathom the notions of number, of space, of time. And above all, their adepts find therein delights analogous to those given by painting and music. They admire the delicate harmony of numbers and forms; they marvel when a new discovery opens to them an unexpected perspective; and has not the joy they thus feel the esthetic character, even though the senses take no part therein? Only a privileged few are called to enjoy it fully, it is true, but is not this the case for all the noblest arts?
This is why I do not hesitate to say that mathematics deserve to be cultivated for their own sake, and the theories inapplicable to physics as well as the others. Even if the physical aim and the esthetic aim were not united, we ought not to sacrifice either.

Unfortunately... the philosophy of Aristotle laid it down as a principle, that the celestial motions were regulated by laws proper to themselves, and bearing no affinity to those which prevail on earth. By thus drawing a broad and impassable line of separation between celestial and terrestrial mechanics, it placed the former altogether out of the pale of experimental research, while it at the same time impeded the progress of the latter by the assumption of principles respecting natural and unnatural motions, hastily adopted from the most superficial and cursory and remark, undeserving even the name of observation. Astronomy therefore continued for ages a science of mere record, in which theory had no part, except in so far as it attempted to conciliate the inequalities of the celestial motions with that assumed law of uniform circular revolution which was alone considered consistent with the perfection of the heavenly mechanism.

Today, after eighteen years of defeat, the book of your domination is again opened, and your first act awakens every unhappy memory, and threatens to destroy the confidence which your professions of patriotism inspired. You turned down a leaf of the history that recorded your last act of power in 1861, and you have now signalized your return to power by beginning a second chapter at the same page, not this time by a heroic act that declares war on the battlefield, but you say, if all the legislative powers of the government do not consent to let you tear certain laws out of the statute-book, you will not shoot our government to death as you tried to do in the first chapter, but you declare that if we do not consent against our will, if you cannot coerce an independent branch of this government, against its will, to allow you to tear from the statute-books some laws put there by "there by the will of the people, you will starve the government to death.

The spirit acquires an increase of knowledge and experience in each of his corporeal existences. He loses sight of part of these gains during his reincarnation in matter, which is too gross to allow of his remembering them in their entirety; but he remembers them as a spirit. It is thus that some somnambulists give evidence of possessing knowledge beyond their present degree of instruction, and even of their apparent intellectual capacity. The intellectual and scientific inferiority of a somnambulist in his waking state, therefore, proves nothing against his possession of the knowledge he may display in his lucid state. According to the circumstances of the moment and the aim proposed, he may draw this knowledge from the stores of his own experience, from his clairvoyant perception of things actually occurring, or from the counsels which he receives from other spirits; but, in proportion as his own spirit is more or less advanced, he will make his statements more or less correctly.
Allan Kardec
When I behold the scientific and so-called philosophers full of selfish feelings, and of a tenency to war against circumstances and Providence, I say to myself: They are not true priests, they are but half prophets - it not absolutely false ones. They have read the great page simply with the physical eye, and with none of the spirit within. The intellectual, the moral, the religious seem to me all naturally bound up and interlinked together in one great and harmonious whole... That God is one, and that all the works and the feelings He has called into existence are ONE; this is a truth (a biblical and scriptural truth too) not in my opinion developed to the apprehension of most people in its really deep and unfanthomable meaning. There is too much tendency to making separate and independent bundles of both the physical and the moral facts of the universe. Whereas, all and everything is naturally related and interconnected. A volume could I write you on this subject.
