“Its (Rasayan’s) principles (certain operations, drugs and compound medicines, most of which are taken from plants) restore the health… and give back youth to fading old age… white hair becomes black again, the keenness of the senses is restored as well as the capacity for juvenile agility, and even for co-habitation, and the life of the people in this world is even extended to a long period.”

“Undoubtedly, as it seems to me at least, satiety of all pursuits causes satiety of life. Boyhood has certain pursuits: does youth yearn for them? Early youth has its pursuits: does the matured or so-called middle stage of life need them? Maturity, too, has such as are not even sought in old age, and finally, there are those suitable to old age. Therefore as the pleasures and pursuits of the earlier periods of life fall away, so also do those of old age; and when that happens man has his fill of life and the time is ripe for him to go.”
Omnino, ut mihi quidem videtur studiorum omnium satietas vitae facit satietatem. Sunt pueritiae studia certa: num igitur ea desiderant adulescentes? Sunt ineuntis adulescentiae: num ea constans iam requirit aetas, quae media dicitur? Sunt etiam eius aetatis: ne ea quidem quaeruntur in senectute. Sunt extrema quaedam studia senectutis: ergo, ut superiorum aetatum studia occidunt, sic occidunt etiam senectutis; quod cum evenit, satietas vitae tempus maturum mortis affert.

Cato Maior de Senectute – On Old Age (44 BC)

Subjectively speaking, the essence of philosophy is certitude; for the moderns, on the contrary, the essence of philosophy is doubt: the philosopher is supposed to reason without any premise (voraussetzungsloses Denken), as if this condition were not itself a preconceived idea; this is the classical contradiction of all relativism. Everything is doubted except for doubt. The solution to the problem of knowledge − if there is a problem − could not possibly be this intellectual suicide that is the promotion of doubt; on the contrary, it lies in having recourse to a source of certitude that transcends the mental mechanism, and this source − the only one there is − is the pure Intellect, or Intelligence as such.

Context: But it will be asked, Is it safe to admit to the elective franchise the great mass of ignorant and degraded blacks, so lately slaves? Here indeed is the great practical question, to the solution of which should be brought all the wisdom and enlightenment of our people. I am fully persuaded that some degree of intelligence and culture should be required as a qualification for the right of suffrage. I have no doubt that it would be better if no man were allowed to vote who cannot read his ballot or the Constitution of the United States, and write his name or copy in a legible hand a sentence from the Declaration of Independence. Make any such wise restriction of suffrage, but let it apply to all alike. Let us not commit ourselves to the absurd and senseless dogma that the color of the skin shall be the basis of suffrage, the talisman of liberty. I admit that it is perilous to confer the franchise upon the ignorant and degraded; but if an educational test cannot be established, let suffrage be extended to all men of proper age, regardless of color. It may well be questioned whether the negro does not understand the nature of our institutions better than the equally ignorant foreigner. He was intelligent enough to understand from the beginning of the war that the destiny of his race was involved in it. He was intelligent enough to be true to that Union which his educated and traitorous master was endeavoring to destroy. He came to us in the hour of our sorest need, and by his aid, under God, the Republic was saved. Shall we now be guilty of the unutterable meanness, not only of thrusting him beyond the pale of its blessings, but of committing his destiny to the tender mercies of those pardoned rebels who have been so reluctantly compelled to take their feet from his neck and their hands from his throat? But someone says it is dangerous at this time to make new experiments. I answer, it is always safe to do justice. However, to grant suffrage to the black man in this country is not innovation, but restoration. It is a return to the ancient principles and practices of the fathers. Let me refer you to a few facts in our history which have been but little studied by' the people and politicians of this generation.
