In this paper, we are trying to summarize the peak of achievement of the Arabian logicians of the fifteenth century by making a classification and sketching in familiar terms the conditional and subjunctive syllogisms in Muḥammad Ibn Yusūf al-SSinūsī’s (1426-1490) work, i.e. in his explanation of Kitāb al-Muḫtaşar fī al-Manṭiq of al-Imām Muḥammad Ibn ʿArafa (1316- 1401).

The form of the conditional syllogism resembles that of the categorical syllogism, while its subject matter is at least a conditional premise, but its conclusion is always conditional conjunctive or disjunctive. This mixed structure to which we apply the rules of the categorical syllogism, is a structure of which Aristotle did not have an idea, and which the Stoics did not conceive, and which the non-Arabian logicians did not know until in modern times. But what we have to notice here (...) is the putting of a conditional matter in the form of the categorical syllogism, and it is this kind of hybridization, if we dare to say, which generated this mixed structure which appeared for the first time in the history of logic in the treatise on the logic of Ibn Sina and which can be considered a discovery by this author until proof to the contrary, and that the ancient Arabian logicians have taken the habit of exhibiting in their treatises.

This paper relies on primary resources dealing with the history of Oman along with British documents, which are the most important materials that dealt with the situation in the region, in general, and in Oman in Particular, at a time when Britain had power, presence and military control over India through the Government of British India. At that time, Britain tried to open lines of communication and forge agreements with the Arabian Gulf countries in order to secure its control over (...) this vital region and secure communications with its colonies in India. This study focuses on the economic and commercial relations between the two countries including trade of spices, textile, weapons, slaves, dates and other goods, the currencies used in these commercial exchanges, and the volume of trade. It also explores the volatility of these relations in different periods. The study also examines the social and cultural relations, mutual migrations, and military and political ties. In addition, it explores various aspects of reciprocal influence between the two areas in different periods and during turbulent times for the sultanate of Oman and the region, prior to, during and after the First World War. It investigates these relations from signing of the treaty of AL-Seeb in 1920 and the stabilization phase it created up to the end of the study period. The study has reached a number of conclusions about the development of these relations and the factors influencing this development at a time when sultan Timor tried to maintain independence in running the country despite the British influence. It also focuses on how the sultan attempted to benefit from Britain’s need to secure shipping lines by enhancing the sultanate’s trade with India until India became the first economic and trade partner with the sultanate during this period. The sultan tried to maintain a friendly relationship with Britain and India, where his currency was mined and where he used to stay for recuperation. (shrink)
