Semiotics

"Scire est nescire, nisi id me scire alius scierit."

"Et teneo melius ista quam meum nomen."

"Scire tuum nihil est, nisi te scire hoc sciat alter?"

"Ego te intus et in cute novi."

"Plus scire satius est, quam loqui."

"Natura semina scientiæ nobis dedit, scientiam non dedit."

"Namque inscitia est, Adversum stimulum calces."

"Faciunt næ intelligendo, ut nihil intelligant."

"Do you know how God controls the clouds and how he causes the lightning to flash from his cloud? Do you know how the clouds float? These are the wonderful works of the One perfect in knowledge."

"They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea."

"Through wisdom is an house builded; and by understanding it is established: And by knowledge shall the chambers be filled with all precious and pleasant riches."

"Many shall run to and fro, and knowledge shall be increased."

"The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge."

"In vain have you acquired knowledge if you do not impart it it to others."

"He that increaseth knowledge increaseth sorrow."

"The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction."

"When wisdom enters your heart"

"Whoever loves discipline loves knowledge."

"O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!"

"O the depth of God’s riches and wisdom and knowledge! How unsearchable his judgments are and beyond tracing out his ways are! For “who has come to know Jehovah’s mind, or who has become his adviser?” Or, “who has first given to him, so that it must be repaid to him?” Because from him and by him and for him are all things. To him be the glory forever. Amen."

"And (mention, O Muhammad), when your Lord said to the angels, "Indeed, I will make upon the earth a successive authority." They said, "Will You place upon it one who causes corruption therein and sheds blood, while we declare Your praise and sanctify You?" He (God) said: Surely, I know what you know not."

"They (angels) said, "Exalted are You; we have no knowledge except what You have taught us. Indeed, it is You who is the Knowing, the Wise.""

"And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight and the heart – about all those (one) will be questioned."

"So high (above all) is God, the Sovereign, the Truth. And, (O Muhammad), do not hasten with (recitation of) the Qur'an before its revelation is completed to you, and say, "My Lord, increase me in knowledge.""

"There is another form of temptation, more complex in its peril. … It originates in an appetite for knowledge. … From this malady of curiosity are all those strange sights exhibited in the theatre. Hence do we proceed to search out the secret powers of nature (which is beside our end), which to know profits not, and wherein men desire nothing but to know."

"Without any delusive representation of images or phantasms, I am most certain that I am, and that I know and delight in this. In respect of these truths, I am not at all afraid of the arguments of the Academicians, who say, What if you are deceived? For if I am deceived, I am. For he who is not, cannot be deceived; and if I am deceived, by this same token I am. And since I am if I am deceived, how am I deceived in believing that I am? for it is certain that I am if I am deceived. Since, therefore, I, the person deceived, should be, even if I were deceived, certainly I am not deceived in this knowledge that I am."

"The one who thinks he knows something does not yet know as he ought to know."

"A name made great is a name destroyed. He who does not increase his knowledge decreases it."

"The knowledge of anything, since all things have causes, is not acquired or complete unless it is known by its causes. Therefore in medicine we ought to know the causes of sickness and health. And because health and sickness and their causes are sometimes manifest, and sometimes hidden and not to be comprehended except by the study of symptoms, we must also study the symptoms of health and disease. Now it is established in the sciences that no knowledge is acquired save through the study of its causes and beginnings, if it has had causes and beginnings; nor completed except by knowledge of its accidents and accompanying essentials. Of these causes there are four kinds: material, efficient, formal, and final."

"Prudens quaestio dimidium scientiae."

"...if perception is only knowledge or a means towards knowledge; since he who perceives, has knowledge thereby, according to the special character of the senses, by sight of colours, by taste of savours and so forth: then whatsoever has knowledge in whatsoever manner may be said without impropriety in some sense to perceive. Therefore, O Lord, although Thou art not a body, yet of a truth Thou hast in this sense perception in the highest degree, since Thou knowest all things in the highest degree; but not in the sense wherein an animal that has knowledge by means of bodily feeling is said to have perception."

"Knowledge comes Of learning well retain'd, unfruitful else."

"The eye with which I see God is the same with which God sees me. My eye and God's eye is one eye, and one sight, and one knowledge, and one love."

"Knowledge comes through likeness. And so because the soul may know everything, it is never at rest until it comes to the original idea, in which all things are one. And there it comes to rest in God."

"For the more a man knows, the more worthy he is."

"You must know that if a person, who has attained a certain degree of perfection, wishes to impart to others, either orally or in writing, any portion of the knowledge which he has acquired of these subjects, he is utterly unable to be as systematic and explicit as he could be in a science of which the method is well known. The same difficulties which he encountered when investigating the subject for himself will attend him when endeavouring to instruct others: viz., at one time the explanation will appear lucid, at another time, obscure: this property of the subject appears to remain the same both to the advanced scholar and to the beginner. For this reason, great theological scholars gave instruction in all such matters only by means of metaphors and allegories."

"sic: si omnes homines natura scire desiderant, ergo maxime scientiam maxime desiderabunt. Ita arguit Philosophus I huius cap. 2. Et ibidem subdit: "quae sit maxime scientia, illa scilicet quae est circa maxime scibilia". Maxime autem dicuntur scibilia dupliciter: uel quia primo omnium sciuntur sine quibus non possunt alia sciri; uel quia sunt certissima cognoscibilia. Utroque autem modo considerat ista scientia maxime scibilia. Haec igitur est maxime scientia, et per consequens maxime desiderabilis."

"You must acquire the best knowledge first, and without delay; it is the height of madness to learn what you will later have to unlearn."

"If thou knewest the whole Bible by heart, and the sayings of all the philosophers, what would it profit thee without the love of God and without grace?"

"Every man naturally desires knowledge; but what good is knowledge without fear of God? Indeed a humble rustic who serves God is better than a proud intellectual who neglects his soul to study the course of the stars."

"Shun too great a desire for knowledge, for in it there is much fretting and delusion. Intellectuals like to appear learned and to be called wise. Yet there are many things the knowledge of which does little or no good to the soul, and he who concerns himself about other things than those which lead to salvation is very unwise."

"He knew what is what."

"I have taken all knowledge to be my province."

"Knowledge is power."

"Knowledge and human power are synonymous, since the ignorance of the cause frustrates the effect."

"Knowledge bloweth up, but charity buildeth up."

"Nam et ipsa scientia potestas est."

"For knowledge, too, is itself a power."

"I find that even those that have sought knowledge for itself, and not for benefit, or ostentation, or any practicable enablement in the course of their life, have nevertheless propounded to themselves a wrong mark, namely, satisfaction, which men call truth, and not operation. For as in the courts and services of princes and states, it is a much easier matter to give satisfaction than to do the business; so in the inquiring of causes and reasons it is much easier to find out such causes as will satisfy the mind of man and quiet objections, than such causes as will direct him and give him light to new experiences and inventions."
