What he perhaps valued highest in his work were his contributions to the defence of Christianity; one of which, in particular, was praised by Hutchinson Stirling and reprinted at the request of Professor Crawford.
His sense of his own unworthiness I have called morbid; morbid, too, were his sense of the fleetingness of life and his concern for death. He had never accepted the conditions of man's life or his own character; and his inmost thoughts were ever tinged with the Celtic melancholy. Cases of conscience were sometimes grievous to him, and that delicate employment of a scientific witness cost him many qualms. But he found respite from these troublesome humours in his work, in his lifelong study of natural science, in the society of those he loved, and in his daily walks, which now would carry him far into the country with some congenial friend, and now keep him dangling about the town from one old book-shop to another, and scraping romantic acquaintance with every dog that passed. His talk, compounded of so much sterling sense and so much freakish humour, and clothed in language so apt, droll, and emphatic, was a perpetual delight to all who knew him before the clouds began to settle on his mind. His use of language was both just and picturesque; and when at the beginning of his illness he began to feel the ebbing of this power, it was strange and painful to hear him reject one word after another as inadequate, and at length desist from the search and leave his phrase unfinished rather than finish it without propriety. It was perhaps another Celtic trait that his affections and emotions, passionate as these were, and liable to passionate ups and downs, found the most eloquent expression both in words and gestures. Love, anger, and indignation shone through him and broke forth in imagery, like what we read of Southern races. For all these emotional extremes, and in spite of the melancholy ground of his character, he had upon the whole a happy life; nor was he less fortunate in his death, which at the last came to him unaware.
CHAPTER X. TALK AND TALKERS
Sir, we had a good talk. - JOHNSON.
As we must account for every idle word, so we must for every idle silence. - FRANKLIN.
THERE can be no fairer ambition than to excel in talk; to be affable, gay, ready, clear and welcome; to have a fact, a thought, or an illustration, pat to every subject; and not only to cheer the flight of time among our intimates, but bear our part in that great international congress, always sitting, where public wrongs are first declared, public errors first corrected, and the course of public opinion shaped, day by day, a little nearer to the right. No measure comes before Parliament but it has been long ago prepared by the grand jury of the talkers; no book is written that has not been largely composed by their assistance. Literature in many of its branches is no other than the shadow of good talk; but the imitation falls far short of the original in life, freedom and effect. There are always two to a talk, giving and taking, comparing experience and according conclusions. Talk is fluid, tentative, continually "in further search and progress"; while written words remain fixed, become idols even to the writer, found wooden dogmatisms, and preserve flies of obvious error in the amber of the truth. Last and chief, while literature, gagged with linsey-woolsey, can only deal with a fraction of the life of man, talk goes fancy free and may call a spade a spade. Talk has none of the freezing immunities of the pulpit. It cannot, even if it would, become merely aesthetic or merely classical like literature. A jest intervenes, the solemn humbug is dissolved in laughter, and speech runs forth out of the contemporary groove into the open fields of nature, cheery and cheering, like schoolboys out of school. And it is in talk alone that we can learn our period and ourselves. In short, the first duty of a man is to speak; that is his chief business in this world; and talk, which is the harmonious speech of two or more, is by far the most accessible of pleasures. It costs nothing in money; it is all profit; it completes our education, founds and fosters our friendships, and can be enjoyed at any age and in almost any state of health.
