“One must not be afraid of new ideas, no matter the source. And we must never fear the truth, even when it pains us.”

“We ought not to be embarrassed of appreciating the truth and of obtaining it wherever it comes from, even if it comes from races distant and nations different from us. Nothing should be dearer to the seeker of truth than the truth itself, and there is no deterioration of the truth, nor belittling either of one who speaks it or conveys it.”

“The noblest part of philosophy and the highest in rank is the First Philosophy, i.e., knowledge of the first truth, which is the cause of all truth. Therefore it is necessary that the most perfect and noble philosopher will be the man who fully understands this most noble knowledge; for the knowledge of the cause is more noble than the knowledge of the effect, since we have complete knowledge of every knowable, only when we have attained full knowledge of its cause.”

“It is proper that our gratitude be great to those who have contributed even a little of the truth, let alone to those who have contributed much truth, since they have shared with us the fruits of their thought, and facilitated for us the true (yet) hidden inquiries, in that they benefited us
by those premises which facilitated our approaches to the truth. If they had not lived, these true principles with which we have been educated, towards the conclusions of our hidden inquiries, would not have been assembled for us, even with intensive research throughout our time. But indeed this has been assembled only in preceding past ages, age after age, until this our time, accompanied by intensive research, necessary perseverance, and love of toil in that.
In the time of one man, even if his life span is extended, his research intensive, his speculatuon subtle and he is fond of perseverance-it is not possible to assemble as much as has been assembled, by similar efforts-of intense research, subtle speculation, and fondness of perseverance-over a period of time many times as long.”

“One way to solve an encrypted message, if we know its language, is to find a different plaintext of the same language long enough to fill one sheet or so, and then we count the occurrences of each letter. We call the most frequently occurring letter the 'first', the next most occurring letter the 'second', the following most occurring letter the 'third', and so on, until we account for all the different letters in the plaintext sample.
Then we look at the ciphertext we want to solve and we also classify its symbols. We find the most occurring symbol and change it to the form of the 'first' letter of the plaintext sample, the next most common symbol is changed to the form of the 'second' letter, and the following most common symbol is changed to the form of the 'third' letter, and so on, until we account for all symbols of the cryptogram we want to solve.”

“We do not find the truth we are seeking without finding a cause; the cause of the existence and continuance of everything is The True One, in that each thing which has being has truth. The True One exists necessarily and therefore beings exist.”
